I wish you luck with your quilt . Years ago I bought a pack of precut quilt squares for a patchwork quilt . Not knowing then about quilting :roll: . I sewed thw squares together , no problem . Then I get the bright idea of using corduroy strips for the back [ dumb idea by the way ]. A friend had given me the corduroy strips . Well I got it together and my daughter used it on her bed [ teenager at the time ]. It frayed so much the back all came apart ! I had even zigzagged it , didn't help . Maybe the fusible interfacing might help . But this will be a very heavy quilt ! This is just one of my goofed up experiences :shock: Good luck , Annie
