I have been reading all these replies and wondering if the fabrics have a type of rubber(for the want of a better word) backing on them as ours in Australia do. I did make one when I first started quilting and I did not put batting in it but backed it with cotton fabric. They were large sqs and I stitched in the ditch and the fabric stuck together in places because of the backing on the fabric. I didn't know any better then but I have since seen quilts made with that fabric. My daughter had it on her bed and washed it a lot because of small children and it faded quite a bit.
I love this site and always eager to read the posts. It is a great learning site. Feels like family.
