Question 1: Describe two different types of hand stitches that can be used to join fabrics permanently. Include their common uses.

Answer: Two common hand stitches for joining fabrics are the running stitch, used for seams and quick repairs, and the backstitch, which provides a strong, secure seam suitable for joining thicker fabrics or for detailed sewing.

Question 2: Explain the difference between a machine-stitched seam and a glued seam in textiles.

Answer: A machine-stitched seam involves sewing fabrics together with a sewing machine, creating a durable and flexible join. A glued seam uses a special textile adhesive to bond fabrics without sewing, which is quicker but less flexible and durable.

Question 3: Identify three different sewing techniques that can be used to join fabrics for decorative purposes.

Answer: Three decorative joining techniques include topstitching, applique, and decorative embroidery stitches such as zigzag or satin stitch.

Question 4: Describe the process of joining two pieces of fabric using a French seam. Why is this method used?

Answer: A French seam involves sewing the fabric with wrong sides together first, trimming the seam allowance, then sewing again with right sides together to enclose raw edges. This creates a neat, durable, and fray-proof finish, ideal for delicate or sheer fabrics.

Question 5: Sketch a simple diagram showing how two fabric pieces are joined using a plain seam. Label the seam and seam allowance areas.

Answer: A correct sketch would display two fabric pieces aligned with their raw edges together, a dashed line indicating the stitching line, and shaded areas representing the seam allowance on both sides.

Question 6: List three advantages of using a fusible web to join fabrics.

Answer: Advantages include quick assembly, no need for sewing skills, and a flat, neat finish suitable for appliqué and hems.

Question 7: Explain how a hem stitch can be used to join two fabric edges temporarily and why it might be useful.

Answer: A hem stitch is a long, loose hand stitch that temporarily holds fabric edges together, useful for fitting adjustments or temporary hems before final sewing.

Question 8: Describe the process of joining fabrics using a zigzag stitch on a sewing machine. What are the benefits of this technique?

Answer: The zigzag stitch involves sewing in a zigzag pattern over raw edges, which helps prevent fraying and allows some stretch in the seam. It is beneficial for stretchy fabrics and finishing raw edges.

Question 9: Draw a design for an overlapping seam used to join two pieces of fabric in a quilt. Indicate where the overlap occurs and how it is finished.

Answer: A correct sketch would show two fabric pieces overlapping along a straight edge, with a visible seam line where they are stitched together. The overlapping area should be clearly marked, with suggestions for finishing such as topstitching or binding if applicable.

Question 10: Describe a scenario where a bonded seam would be preferred over a stitched seam. Include reasons for your choice.

Answer: A bonded seam is preferred in waterproof or water-resistant textiles, such as raincoats, because it creates a waterproof join without stitching holes that can allow water to pass through. It is also used to achieve a clean, smooth finish.
