Question 1: Describe how a machine sewing stitch is used to join two pieces of fabric together. Include in your answer the type of stitch and its typical use.

Answer: A machine sewing stitch, such as a straight stitch, is used to join fabric edges by passing the needle and thread through both layers in a straight line. It provides a strong, secure seam suitable for most woven fabrics.

Question 2: Explain the main difference between hand sewing and machine sewing when joining fabrics.

Answer: Hand sewing involves manually passing a needle and thread through fabric, offering greater control and detail, while machine sewing uses a sewing machine to create faster, more uniform stitches over larger areas.

Question 3: List three common types of seams used in textiles and briefly describe each.

Answer: 1. Plain seam: The most basic seam where fabric edges are sewn together and pressed open. 2. French seam: Encases raw edges within a double seam for a neat finish, often used in delicate fabrics. 3. Flat-felled seam: Overlocked and topstitched to enclose raw edges, providing durability, commonly used in denim.

Question 4: Identify a situation where an overcast stitch might be used in joining fabrics and explain why.

Answer: An overcast stitch is used to prevent raw fabric edges from fraying, especially in seams that are not finished with other seam types or for raw edge seams in woven fabrics.

Question 5: Sketch a simple diagram of a basic hand stitch used to join two pieces of fabric. Label the parts of the stitch, including the needle, thread, and fabric edges.

Answer: A correct sketch would show two pieces of fabric placed edge to edge, with the needle passing through both fabrics, and thread forming small, evenly spaced stitches along the seam line. Labels should include 'needle', 'thread', and 'fabric edges'.

Question 6: Describe how a fusible web can be used to join fabrics and mention one advantage of using it.

Answer: Fusible web is an adhesive bonding material that, when heated with an iron, melts and bonds two fabric surfaces together without sewing. An advantage is that it creates a quick, clean join without visible stitches.

Question 7: Sketch a diagram showing how a double-stitched seam differs from a single seam. Include labels for each seam type.

Answer: The sketch should show two fabric pieces joined by a double line of stitches for the double-stitched seam, with an inset showing a single line for the single seam. Labels should indicate 'single seam' and 'double-stitched seam'.

Question 8: Explain the purpose of using a hem stitch when joining fabric edges in finishing a garment.

Answer: A hem stitch is used to fold and secure raw fabric edges at the garment's edge, providing a clean finish and preventing fraying while adding durability.

Question 9: Draw a diagram illustrating a zigzag stitch and describe its typical uses in textiles.

Answer: The diagram should show a zigzag pattern of stitches crossing the fabric edge. Uses include finishing raw edges to prevent fraying, sewing stretchy fabrics, and decorative purposes.

Question 10: Identify and describe one method to join two different types of fabrics, such as cotton and polyester, ensuring a durable seam.

Answer: Using a stretch or reinforced seam with a zigzag stitch or serging can effectively join cotton and polyester, providing flexibility and durability while accommodating different fabric properties.
