- A standard household iron used alone with no steam
- A steam iron followed by pounding with a tailor's clapper (Correct answer)
Correct answer: A steam iron followed by pounding with a tailor's clapper
Applying steam with an iron to add moisture, then pounding immediately with a clapper, traps steam in the fibers and creates a sharp crease that holds significantly longer than steam alone.
Question 17: When two pieces of fabric are sewed together, the line formed is known as ________.
- Placket
- Patch
- Seam (Correct answer)
Correct answer: Seam
When two pieces of fabric are sewn together, the line formed by the stitches is known as a seam. Seams are fundamental to garment construction, joining individual pattern pieces to create the three-dimensional form of clothing. They can vary in type and finish depending on the garment's design and fabric.
Question 18: What does OSHA require of tailoring workplaces in the US regarding needle and sharp tool safety?
- OSHA regulations do not apply to small tailoring businesses with under 10 employees

Correct answer: Sharps must be properly stored, disposed of safely, and workstations maintained to prevent puncture injuries
OSHA standards require that workplaces with sharp hazards provide proper storage, safe disposal containers, and training to prevent injury.
Question 19: When should seams generally be pressed during garment construction?
- Before any fabric pieces are cut from the pattern
- Only at the very end when the entire garment is complete
- Only when the fabric type specifically requires pressing
- As each seam is sewn, before joining to another piece (Correct answer)
Correct answer: As each seam is sewn, before joining to another piece
In professional tailoring, each seam is pressed immediately after sewing to set the stitches and prepare the area for the next construction step.
Question 20: A trainee struggles to understand grainline. How should a trainer explain it?
- Grainline doesn't matter
- It only applies to knits
- It is the direction of the warp threads and pattern pieces must align to it (Correct answer)
- It is the same as the selvage edge color
Correct answer: It is the direction of the warp threads and pattern pieces must align to it
Grainline follows the warp threads and proper alignment ensures the garment hangs correctly.
Question 21: What is a 'welt pocket' in tailoring?
- A patch pocket stitched on the outside of the garment
- A kangaroo-style pocket on the front of the garment
- A pocket opening finished with folded strips of fabric forming a slit (Correct answer)
- A hidden pocket sewn into the side seam
Correct answer: A pocket opening finished with folded strips of fabric forming a slit
A welt pocket is formed by a slit opening finished with one or two narrow fabric strips (welts) that frame the pocket opening neatly.
Question 22: What is the recommended way to mark darts and dots transferred from a pattern onto delicate fabric?
- Tailor's tacks or chalk that brush or wash out (Correct answer)
- A hot iron crease
- Permanent ink pen
- Cut small notches through both layers
Correct answer: Tailor's tacks or chalk that brush or wash out
Tailor's tacks and removable chalk transfer marks without permanently damaging or staining delicate cloth.
Question 23: What does the term 'grain line' refer to in fabric?
- The thread count per inch
- The width of the selvage
- The direction of the warp threads (Correct answer)
- The bias cut angle
Correct answer: The direction of the warp threads
The grain line runs parallel to the warp (lengthwise) threads and determines how the fabric hangs.
Question 24: What is the standard seam allowance used in most tailored garments?
- 2 inches (5 cm)
- 1 inch (2.5 cm)
- 1/4 inch (6 mm)
- 5/8 inch (1.5 cm) (Correct answer)
Correct answer: 5/8 inch (1.5 cm)
The standard seam allowance in tailoring is 5/8 inch (1.5 cm), which provides enough fabric to sew a secure seam while still allowing for fitting adjustments.
Question 25: What does a professional tailor do with a client's measurements after recording them?
- Store them in a secure client record file for future orders and alterations (Correct answer)
- Share them with other tailors for benchmarking
- Discard them after the job is completed
- Post them publicly for marketing purposes
Correct answer: Store them in a secure client record file for future orders and alterations
Client measurements are confidential personal data and should be stored securely in the client's record file so they can be referenced for future work, saving time at subsequent appointments.
Question 26: Which of the following fabrics is crease-resistant for men's trousers?
- Polyester
- Worsted tool
- Denim (Correct answer)
- Corduroy
Correct answer: Denim
Denim is a durable and sturdy cotton twill fabric widely known for its crease-resistant properties, especially in its heavier weights. Its tightly woven structure helps it maintain its shape and resist wrinkling, making it an excellent choice for men's trousers that need to withstand regular wear and maintain a neat appearance.
Question 27: Why should fabric shears never be used to cut paper?
- Paper dulls the blades (Correct answer)
- It bends the handles
- Paper stains the metal
- It rusts the screw
Correct answer: Paper dulls the blades
Paper quickly dulls fine fabric-cutting blades, ruining clean cuts on cloth.
Question 28: What is a 'trouser break' in tailoring?
- A press crease running down the front of the trouser leg
- A vent cut into the back of the trouser hem
- The slight fold or crease where the trouser leg rests on the shoe (Correct answer)
- The point where the trouser waistband meets the fly
Correct answer: The slight fold or crease where the trouser leg rests on the shoe
The trouser break is the amount of fabric that folds or 'breaks' at the shoe top, affecting the formality of the finished look.
Question 29: When drafting a collar pattern, what is the 'neckline seam length' used for?
- To calculate the amount of interfacing required for the collar
- To determine the width of the collar stand
- To ensure the collar's lower edge matches the jacket neckline and attaches without puckering (Correct answer)
- To set the height of the collar above the neckline
Correct answer: To ensure the collar's lower edge matches the jacket neckline and attaches without puckering
The collar's lower edge must match the exact length of the neckline seam so the collar attaches smoothly without gathering or stretching.
Question 30: What is 'grading' seam allowances in a garment?
- Adding ease to seam lines for larger sizes
- Increasing the seam allowance for fitting adjustments
- Trimming each seam allowance layer to a different width to reduce bulk (Correct answer)
- Marking size gradations on a pattern
Correct answer: Trimming each seam allowance layer to a different width to reduce bulk
Grading seam allowances means trimming each layer to a different width so that when the seam is turned, there is a smooth graduation of fabric rather than a thick lump.
