I am finding I am piecing almost exclusively with my walking foot. I have a 1/4 inch foot (bernina 450) but it still seems to "bunch" the fabric so the ends dont come out even--even on short pieces. I have tried adjusting the presser foot tension but it doesnt seem to have any effect. Anyone else use a walking foot for piecing? It works for me so will probably continue to do this. Just feel sorry for that cute little 1/4 foot not seeing any action!
