I saw a long arm quilter on our local public access channel. She made a booklet, so to speak, of these very similar FMQ patterns. She had quite a few. She used grommets so the fabric wouldn't fray for the rings. She also used heavy cardboard for the outside covers. The made 12" blocks pages. She also used old sheets or fabric she didn't like but the fabric design determined a lot of echoing. She said she could add to it easily because of the rings. Would love to see your finished quilt. The booklet would be a good tool/reference to have on hand.
