Since you use a foundation for crazy quilt blocks, to avoid having my crazy quilt be so heavy when done (it is king-size), I used Bounty paper towel sheets (11 X 11 size) as the foundation backing; they stay in the quilt, and since Bounty is a very strudy towel, it goes through the wash without any issues...just an option for you. I did have my quilt quilted by a long-arm quilter with light batting rather than tying, but I didn't add dimensional embellishments, just decorative stitching over all the seams. The quilt I am talking about is my avatar.
