- It keeps fabric edges from coming apart and makes them look neat.
- What are some examples of edge finishing?
- Hemming, zigzag stitches, and bias tape are examples.
- How does hemming help?
- Hemming folds the fabric edge and stitches it down, making it neat and strong.
- What does a presser foot do?
- The presser foot holds the fabric in place while sewing.
- Why do we use a zigzag stitch?
- A zigzag stitch helps to stop the fabric edges from fraying.
- What is the function of the needle in a sewing machine?
