Can you use straight stitch on stretch fabric?
When sewing knits with a straight stitch, stretch the fabric slightly (and gently) as it goes under the presser foot. To do this, apply equal pressure on both sides of the needle by slightly pulling the fabric.
Do you need special thread for stretchy fabric?
All-purpose polyester thread will work fine as it has some give when stretched. Cotton thread is not recommended. If the item you’re making needs to be stretchy or form-fitting to the body, you may want to use elastic thread. Only use elastic thread in the bobbin of your sewing machine, and wind it by hand.
Can you sew elastic with a straight stitch?
You can stitch elastic straight onto your piece of fabric using a straight or zigzag stitch. When you’re making a waistband, join the elastic together first to the correct length.
