In this tutorial, we learn how to edge finish with lingerie elastic. First, grab your elastic and place it onto your fabric. Line up the elastic so it matches in perfectly with the fabric. Use a sewing machine to sew the elastic onto the fabric. Go slowly while you are doing this and lift the elastic in your hand as you continue to sew it on the fabric. When you get to the end of the fabric, the elastic will be sewn on, and you will be able to wear it! This only takes a few minutes, just make sure to take your time when you are sewing this on.
