I used spool of white thread and a red bobbin thread to see which thread is doing what. You are sewing off into nothing on the right so that was a bit tricky to catch just the edge of the folded sandwich back on the left. The machine missed a stitch on the fold which left a unsewn spot. I had to remove the sandwich at the corner and start down the next side so the threads would need to be tied off and buried at the corners. This method might come in handy sometime.[ATTACH=CONFIG]536513[/ATTACH]
