Have any of you ever used elastic thread in your sewing machine? I saw a cute scarf at the mall. It was only a piece of fleece with two rows of elastic thread down each side so it kind of ruffled up. It was $38 (but it was a Vera wang). It would be so easy to make. They have the thread at Joann's. It says to hand wind the bobbin but I wondered if anyone has experience with it and some tips to give.
