Question 1: Describe the process of using a straight stitch to join two pieces of fabric on a sewing machine. Include key steps and considerations.

Answer: To use a straight stitch, align the fabrics with the edges together, set the sewing machine to a straight stitch, and sew along the edge, maintaining a consistent seam allowance. Backstitch at the beginning and end to secure the stitches, and press the seam afterwards.

Question 2: Explain the advantages of using a French seam when joining fabrics, especially for delicate or lightweight materials.

Answer: A French seam encloses the raw edges within the seam, preventing fraying and providing a neat, professional finish. It is ideal for delicate fabrics as it reduces damage and gives added durability.

Question 3: Identify two different types of hand stitches that can be used to join fabrics and describe when each might be preferred.

Answer: The slip stitch is useful for hemming or closing seams invisibly, especially on delicate fabrics. The backstitch is strong and suitable for securing seams that need to withstand stress.

Question 4: Sketch a diagram demonstrating how to create a flat-felled seam. Label the key steps and the parts of the finished seam.

Answer: A correct sketch would show two fabric edges sewn together with raw edges enclosed within the seam, folded and stitched down to create a flat, durable finish. Labels should include: initial seam, enclosure of raw edges, topstitching.

Question 5: Discuss the purpose and method of using a zigzag stitch to join fabrics. How does it compare to a straight stitch?

Answer: A zigzag stitch is used to join stretch fabrics or to prevent fraying of raw edges. It allows flexibility and provides a more secure finish on stretchy or fraying fabrics. Compared to a straight stitch, it is more adaptable to fabrics that require movement or extra durability.

Question 6: Describe how to reinforce a seam to ensure durability when joining heavy or thick fabrics.

Answer: Reinforcement can be achieved by sewing multiple rows of stitches, using a zigzag stitch over the seam allowance, or adding interfacing or reinforcement tape along the seam for additional strength.

Question 7: Sketch a design for a fabric join that uses a binding technique. Include the placement of the binding and how it secures the seam.

Answer: A correct sketch would show two fabric edges joined with a strip of binding tape folded over the raw edges, stitched in place along the edges, creating a neat, finished seam with the binding visible on the outside or inside depending on style.

Question 8: Explain the purpose of using a fusible web to join fabrics and describe the basic method of application.

Answer: Fusible web is used to bond fabrics without sewing, providing a quick and clean join. It is applied by placing the web between two fabric pieces and applying heat with an iron, which melts the adhesive and fuses the fabrics together.

Question 9: Identify and explain two considerations when choosing a joining technique for a project that involves stretch fabrics.

Answer: First, the technique should allow some stretch, such as a zigzag stitch or stretch seam, to prevent restricting movement. Second, the method should minimize fraying and maintain fabric flexibility, ensuring the seam remains durable during movement.

Question 10: Draw a simple diagram showing how to join two pieces of fabric with an overlock stitch. Label the parts of the overlocked seam.

Answer: A correct diagram would depict two fabric edges sewn with an overlock stitch, with the overlock thread wrapping around the raw edges, preventing fraying. Labels should include: overlock stitch line, raw edge, and the overlock threads wrapping around the edge.
