I am just finishing a vest and would like to try a different way of putting it together. I would like to make an inside seam like sewing--only with yarn. Could any of you tell me how to hold the pieces together (can't use pins because of the thickness of the knitted pieces). What would some of you use to hold it so that I could work ? I would say toothpicks but I am afraid that would snag the yarn. Any ideas? Since there isn't much activity here, it will probably take a while to get an answer. Thanks in advance. Barb
