Second, time to shir. I took my elastic thread and hand wound it around my bobbin. I was trying to do this quickly, so I didn't look up any instructions. I put the bobbin in my machine, changed the top thread to match and sewed four parellell lines on the strip of fabric. I was pleased with how it looked, but it was a little weird and twisty, that is until I put my iron to it. Then it did just what elastic thread is supposed to do. Fun Fun.
