Answer:
Stretch stitch
Step-by-step explanation:
A stretch stitch is a type of sewing machine stitch that is specifically designed to be used on stretchy or flexible fabrics, such as knit fabrics. It is similar to a zigzag stitch in that it has a bit of stretch to it, which allows it to move with the fabric and prevents the seam from tearing again. To repair a ripped seam in a knit fabric using a stretch stitch, first, re-align the edges of the seam as closely as possible. Then, use a sewing machine to sew a stretch stitch along the seam, making sure to catch both sides of the seam in the stitch. This will reinforce the seam and help to prevent it from tearing again.
