Well it has taken me a week to unpick but I have done it, success! A lesson in why not to be impatient! After unpicking it all, I ironed it, taped the backing down firmly, instead of skipping that part totally like before. Used my long 24 inch ruler to smooth the wadding and top layer as I place each one down, skipped that bit before. Pinned it about 2 - 3 inches apart instead of like 5 - 6 inches before. Changed the thread to 100% cotton rather than the cheap polyester thread I was trying to use up! Stitch length to 3.5, pressure foot to 3 and wolah, machine quilting success. I have the binding on ready to hand sew down while watching telly this week.
