I have been quilting for over 20 yrs and was taught to stack masking tape several layers thick, be sure that the edges are straight, find the 1/4 inch and place the tape. 20 yrs later I still use that method..even if I have a quarter inch foot.
This is the method that worked best when I gave summer camp sewing lessons. Each student had a different machine so just adding tape worked just fine. These were children 8 - 12 yrs old. It was lots of fun we tied the comforters and I bound them on the machine.[ATTACH=CONFIG]567005[/ATTACH]
