Q1. Which tool is used to mark fabric with temporary lines that disappear after sewing or washing?
- A. Seam ripper
- B. Tailor's chalk ✓
- C. Pinking shears
- D. Bodkin
Why: Tailor's chalk leaves temporary marks on fabric that brush off or fade, making it ideal for marking pattern lines, darts, and hems without permanently damaging the garment.
Q2. What is the main purpose of a seam ripper?
- A. To cut fabric in a zigzag edge
- B. To measure the length of a seam
- C. To carefully remove stitches ✓
- D. To press seams flat
Why: A seam ripper has a small, sharp point designed to cut and lift stitches so you can undo mistakes or unpick seams without damaging the fabric.
Q3. Which type of scissors should be used only for cutting fabric, never paper?
- A. Embroidery scissors
- B. Paper scissors
- C. Dressmaking shears ✓
- D. Thread snips
Why: Dressmaking shears have long, sharp blades designed to cut cleanly through fabric. Cutting paper dulls the blades quickly, so they should be reserved for fabric only.
Q4. What is the function of a pin cushion?
- A. To hold bobbins while sewing
- B. To store pins and needles safely and within easy reach ✓
- C. To measure hem allowances
- D. To guide fabric under the presser foot
Why: A pin cushion keeps pins and needles organized, accessible, and off the work surface, reducing the risk of losing them or accidentally pricking yourself.
Q5. Which tool is used to measure curved body contours such as around the bust or hips?
- A. Ruler
- B. Hem gauge
- C. Flexible measuring tape ✓
- D. Set square
Why: A flexible measuring tape can bend and conform to the body's curves, giving accurate circumference and length measurements that a rigid ruler cannot provide.

Q1. Which fiber is a natural protein fiber commonly used for luxurious, drapey garments?
- A. Polyester
- B. Silk ✓
- C. Rayon
- D. Nylon
Why: Silk is a natural protein fiber produced by silkworms. It is prized for its sheen, drape, and comfort, while polyester, rayon, and nylon are synthetic or semi-synthetic fibers.
Q2. Which fabric type is best suited for beginners learning to sew because it is stable and does not slip easily?
- A. Chiffon
- B. Satin
- C. Cotton broadcloth ✓
- D. Charmeuse
Why: Cotton broadcloth is a tightly woven, stable fabric that is easy to cut, handle, and stitch. Chiffon, satin, and charmeuse are slippery or lightweight fabrics that are difficult for beginners to control.
Q3. What does the term 'grain' refer to when selecting fabric for a pattern?
- A. The fabric's color depth
- B. The direction of the threads in the woven fabric ✓
- C. The weight of the fabric per square yard
- D. The softness of the fabric surface
Why: Grain is the direction of the lengthwise (warp) and crosswise (weft) threads in woven fabric. Pattern pieces are aligned to the grain so the garment hangs correctly and does not twist or stretch unevenly.
Q4. Which property describes a fabric's ability to stretch and recover its shape?
- A. Drape
- B. Elasticity ✓
- C. Luster
- D. Absorbency
Why: Elasticity is the ability of a fabric to stretch and return to its original shape. Knit fabrics and fabrics containing spandex typically have high elasticity, while drape describes how fabric falls and flows.
Q5. Which fabric is generally recommended for a beginner's first project involving a heavy coat or structured jacket?
- A. Lightweight voile
- B. Silk crepe de chine
- C. Wool melton ✓
- D. Organza
Why: Wool melton is a dense, heavy, and stable woolen fabric suited to coats and structured outerwear. Voile, crepe de chine, and organza are lightweight, sheer, or delicate and are better suited to blouses and dresses.

Module 3: Hand Sewing Stitches
Hand Sewing Stitches
Knowledge check
Q1. Which hand stitch is most commonly used to temporarily hold layers of fabric together before machine sewing?
- A. Running stitch
- B. Basting stitch ✓
- C. Backstitch
- D. Blind stitch
Why: Basting stitch is a long, loose temporary stitch used to hold fabric pieces in place before final stitching. It is easy to remove once the permanent seam is sewn.
Q2. What is the main purpose of the running stitch?
- A. To create a strong, permanent seam that bears heavy stress
- B. To make a simple, evenly spaced stitch for gathering, mending, or light seaming ✓
- C. To hem garments invisibly from the outside
- D. To attach buttons securely to a garment
Why: The running stitch is a simple in-and-out stitch with evenly spaced stitches, used for seams, gathering, and basic mending. It is quick and beginner-friendly.
Q3. Which stitch creates the strongest hand-sewn seam by overlapping each stitch backward over the previous one?
- A. Whipstitch
- B. Slip stitch
- C. Backstitch ✓
- D. Running stitch
Why: The backstitch works by taking each stitch back over the previous one, creating a continuous line with no gaps. This makes it much stronger than a running stitch and suitable for stressed seams.
Q4. Which stitch is typically used to hem a garment so the stitches are nearly invisible from the right side?
- A. Slip stitch ✓
- B. Running stitch
- C. Basting stitch
- D. Overcast stitch
Why: The slip stitch catches just a few threads of the garment fabric and then runs inside the hem fold, leaving the outside almost invisible. It is the standard choice for hand-finished hems.
Q5. What is the main difference between a whipstitch and an overcast stitch?
- A. A whipstitch is used on knits, while an overcast stitch is used on woven fabrics
- B. A whipstitch joins two edges together, while an overcast stitch covers a raw edge to prevent fraying ✓
- C. A whipstitch is always done by machine, while an overcast stitch is always by hand
- D. There is no difference; the two names describe the same stitch
Why: A whipstitch is used to join two edges, such as in closing a seam or stitching a felt piece. An overcast stitch wraps diagonally over a single raw edge to keep it from fraying.

Module 4: Using the Sewing Machine
Using the Sewing Machine
Knowledge check
Q1. What is the main purpose of the presser foot on a sewing machine?
- A. To cut the fabric as you sew
- B. To hold the fabric flat against the feed dogs while stitching ✓
- C. To wind the bobbin thread
- D. To adjust the stitch length
Why: The presser foot applies downward pressure to hold the fabric in place so the feed dogs can move it smoothly under the needle, producing even stitches.
Q2. Which part of the sewing machine moves the fabric forward through the machine?
- A. The bobbin case
- B. The tension dial
- C. The feed dogs ✓
- D. The handwheel
Why: The feed dogs are the metal teeth beneath the needle plate. They grip the fabric and move it forward in small increments with each stitch.
Q3. What does a stitch length setting of 2.5 mm typically produce?
- A. A very tight, short stitch used for buttonholes only
- B. A standard, medium-length straight stitch suitable for most general sewing ✓
- C. A long basting stitch used for temporary seams
- D. A zigzag stitch for finishing edges
Why: A stitch length around 2.5 mm is a common default for general-purpose straight stitching on medium-weight fabrics, balancing strength and appearance.
Q4. What is the correct way to lower the needle into the fabric before starting to sew?
- A. Turn the handwheel toward you until the needle is at its highest point and then pull the fabric
- B. Turn the handwheel toward you to lower the needle into the fabric's starting point before pressing the foot pedal ✓
- C. Press the foot pedal first and let the machine lower the needle automatically
- D. Lift the presser foot and insert the needle directly into the fabric by hand
Why: Turning the handwheel toward you (counterclockwise on most machines) lets you position the needle precisely at the starting point without the machine running, which helps you begin sewing accurately.
Q5. Why is it important to use the correct needle size for your fabric?
- A. A larger needle always gives a neater stitch on any fabric
- B. The needle size only affects the thread color
- C. Using the wrong needle can cause skipped stitches, fabric damage, or puckering ✓
- D. Needle size has no effect on the finished seam
Why: Needles must match fabric weight: a needle too fine for heavy fabric can break, while one too heavy for delicate fabric can leave holes or pull threads, causing skipped stitches and puckering.
Module 5
Module 5: Reading Patterns and Taking Measurements
Reading Patterns and Taking Measurements
Knowledge check
Q1. What does the term 'ease' refer to in dressmaking patterns?
- A. The difficulty level of a sewing project
- B. Extra room added to a pattern so the garment can move comfortably and fit over the body ✓
- C. The speed at which fabric feeds through the sewing machine
- D. The tightness of the stitches used in seams
Why: Ease is the additional measurement built into a pattern beyond the body measurement. It allows for movement, breathing, and comfort. Negative ease, used in stretch fabrics, is the opposite and makes the garment smaller than the body measurement.
Q2. Which measurement should you take to determine the correct bust size for a pattern?
- A. Around the waist, at the narrowest point
- B. Around the fullest part of the bust, keeping the tape level and snug but not tight ✓
- C. From the shoulder to the hem
- D. Across the back from one shoulder seam to the other
Why: The bust measurement is taken around the fullest part of the chest, with the tape held parallel to the floor. It should be snug without compressing the body, since this measurement directly determines the pattern size you select.
Q3. What do the notches on a sewing pattern piece indicate?
- A. Where to cut the fabric with scissors
- B. Points where pattern pieces should be matched and aligned during construction ✓
- C. The location of buttonholes only
- D. The grain direction of the fabric
Why: Notches are small triangular or diamond-shaped marks along the seam edges. They help you line up pattern pieces accurately when sewing, such as matching a sleeve to an armhole, ensuring the parts fit together correctly.
Q4. What does a pattern marking showing a double-headed arrow with 'grainline' mean?
- A. Cut the fabric on a fold
- B. Align this line parallel to the selvage or lengthwise threads of the fabric ✓
- C. Sew this edge with a double stitch
- D. Place this piece on the bias at a 45-degree angle
Why: The grainline arrow shows how to position the pattern piece on the fabric so it runs parallel to the selvage, which is the lengthwise grain. Following it keeps the garment hanging properly and prevents distortion.
Q5. When taking body measurements for a pattern, why is it important to wear the undergarments you plan to wear with the finished garment?
- A. Undergarments are required by pattern companies for legal reasons
- B. They change your shape and measurements, so taking measurements with them gives a more accurate fit ✓
- C. They make the tape measure easier to read
- D. Fabric shrinks when it touches undergarments
Why: Bras, shapewear, and other undergarments alter your silhouette and measurements. Measuring while wearing the intended undergarments ensures the pattern accounts for the actual shape the garment will be worn over.

Module 6: Cutting and Pinning Fabric
Cutting and Pinning Fabric
Knowledge check
Q1. Before cutting, what is the main purpose of pre-washing and pressing fabric?
- A. To make the fabric softer to the touch
- B. To remove sizing and prevent shrinkage after the garment is made ✓
- C. To change the color of the fabric
- D. To make the fabric easier to fold for storage
Why: Many fabrics contain sizing or will shrink when first laundered. Pre-washing and pressing them before cutting ensures the finished garment will not change size or shape after its first wash.
Q2. What does the term 'grainline' refer to in pattern layout?
- A. The direction of the fabric's printed design
- B. The direction of the lengthwise threads parallel to the selvage ✓
- C. The line where the fabric was folded at the mill
- D. The stitch line sewn at the seam allowance
Why: The grainline is the lengthwise direction of the woven fabric, parallel to the selvage. Aligning the pattern piece's grainline arrow with this direction helps the garment hang correctly and prevents distortion.
Q3. Why are pins placed perpendicular to the edge of a pattern piece when pinning it to fabric?
- A. Perpendicular pins are easier to find later
- B. It allows pins to be removed quickly as you cut and reduces the chance of cutting into them ✓
- C. Perpendicular pins make the fabric stretch evenly
- D. It prevents the paper pattern from tearing
Why: Placing pins perpendicular to the cutting line lets you remove them easily as you cut, and keeps the pin heads outside the cutting path, reducing the risk of hitting a pin with your shears.
Q4. Which cutting tool is generally recommended for cutting fabric cleanly without lifting it off the table?
- A. Rotary cutter used on a cutting mat only
- B. Long-bladed dressmaking shears with long, smooth strokes ✓
- C. Craft scissors with short blades
- D. Pinking shears used for every cut
Why: Long-bladed dressmaking shears allow long, smooth cuts while the fabric stays flat on the table, producing accurate edges. Short scissors cause choppy cuts and can lift the fabric, distorting the line.
Q5. What is the purpose of notches marked on a commercial sewing pattern?
- A. They show where to place buttons
- B. They indicate where pieces should match up when sewing, and are transferred to the fabric before the pattern is removed ✓
- C. They show the hem length
- D. They mark the fabric's right side only
Why: Notches are small triangles or marks that help align pattern pieces during sewing, such as matching a sleeve to an armhole. They are cut outward into the seam allowance and transferred to the fabric so the matching points remain visible.

Q1. What is the standard seam allowance used for most garment construction in commercial patterns in the United States?
- A. 1/4 inch (6 mm)
- B. 5/8 inch (1.5 cm) ✓
- C. 1 inch (2.5 cm)
- D. 1/2 inch (1.25 cm)
Why: Most commercial patterns use a 5/8 inch (1.5 cm) seam allowance, which provides enough fabric for sewing, pressing, and finishing seams while allowing room for minor fitting adjustments.
Q2. Which stitch is typically used to temporarily hold layers of fabric together before permanent stitching?
- A. Zigzag stitch
- B. Basting stitch ✓
- C. Blind hem stitch
- D. Overlock stitch
Why: A basting stitch is a long, loose straight stitch used to temporarily join fabric pieces for fitting or alignment. It is removed after the permanent seam is sewn.
Q3. What is the purpose of clipping or notching curved seam allowances before turning a garment right side out?
- A. To shorten the seam length
- B. To reduce bulk and allow the curve to lie smoothly ✓
- C. To mark the grainline
- D. To prevent the fabric from fraying in the wash
Why: Curved seams, such as necklines and armholes, have seam allowances that can bunch up when turned. Clipping concave curves or notching convex curves removes excess fabric so the seam lies flat and smooth.
Q4. Which finishing technique involves folding a raw edge under twice and stitching it to create a clean hem?
- A. Serging
- B. Pinking
- C. Double-fold hem ✓
- D. Bias binding
Why: A double-fold hem turns the raw edge under twice, enclosing it completely, which gives a neat, durable finish that prevents fraying.
Q5. Why is it important to press each seam as you sew a garment rather than only pressing at the end?
- A. Pressing darkens the fabric color
- B. Pressing sets stitches and creates crisp, professional seams and shapes ✓
- C. Pressing removes the need for seam allowances
- D. Pressing shrinks the fabric to the correct size
Why: Pressing as you go sets the stitches into the fabric, helps seams lie flat, and shapes the garment accurately, which results in a more polished and professional final product.
