I've thought of doing this many times, will follow the thread as I as yet have not managed it. I tried pins but they are very difficult to get through wadding/batting in a straight line. Whether something like a u shaped staple would work as they are shorter and don't move as much.raid a tool box some can be 1" long. But these in the back top and bottom stretch backing fabric and fasten down ensuring you can see staple all the time. Cover smooth and push staples through batting. Now put on top positioning staples first then rest of quilt. Top.
this works in my head not sure about practically.
