Question 1: Describe two different types of seams used to join two pieces of fabric. Include how they are constructed and where they might be used.

Answer: A plain seam is stitched along the edges of fabrics with right sides together, then pressed open; commonly used in clothing. A French seam encloses raw edges by sewing the fabric twice, suitable for delicate or transparent fabrics.

Question 2: Explain the purpose of a topstitch when joining fabric pieces. How does it improve the strength or appearance of the seam?

Answer: A topstitch is sewn on the right side of the fabric close to the seam line to reinforce the seam, prevent fraying, and add decorative detail. It enhances durability and visual appeal.

Question 3: Identify two different types of fasteners used in textiles to join or secure fabric pieces. Describe their typical applications.

Answer: Buttons are used to fasten garments or accessories, often for decorative purposes. Velcro is a hook-and-loop fastener suitable for quick fastening in sportswear or children's clothing.

Question 4: Draw a sketch of a simple overlock stitch as it might appear on the edge of a fabric. Label the parts of the stitch.

Answer: A correct sketch should show multiple interlocking loops along the edge of the fabric, with labels indicating the needle thread, looped threads, and fabric edge.

Question 5: Describe the process of joining two fabric pieces using a zigzag stitch. Mention the advantages of this method.

Answer: Place the fabric edges together and sew along the edge using a zigzag stitch. This method allows some stretch, prevents fraying, and is suitable for knit fabrics.

Question 6: Sketch a diagram illustrating a fabric joint created by a double-stitched seam. Indicate where the stitches are and how the fabrics are aligned.

Answer: The diagram should show two fabric pieces joined with two parallel lines of stitching along the seam, with fabric edges aligned and stitches evenly spaced.

Question 7: List three factors to consider when choosing a joining method for a textile project.

Answer: Type of fabric (woven, knit, delicate), intended use and durability, and the desired appearance or finish.

Question 8: Explain how a hem can be used as a joining method and where it might be applied.

Answer: A hem involves folding the fabric edge inward and sewing it down to finish the edge, often used at the bottom of skirts, curtains, or sleeves for a clean, finished look.

Question 9: Sketch a simple illustration of a fabric joint using a flat-felled seam. Label the key features of this seam.

Answer: The sketch should show two fabric edges sewn together with an extra fold and stitching that encloses raw edges, forming a durable seam commonly used in jeans.

Question 10: Describe the advantages of using a binding tape or bias tape when joining fabric edges.

Answer: Binding tape provides a neat finish, covers raw edges to prevent fraying, and adds decorative detail. It’s flexible and suitable for curved edges.
