I made one a few years ago that the rings were printed on a fusible web, where you just layed your fabric pieces onto this fusible web. (it was in the shape of 1/4th of the ring) and then sew it right onto the web. Then you just press the fusible 1/4 rings onto the backing and OooLala....the block was finished. It was a booklet written by "Mary Pat Henderson". She also designed the fusible stuff. It was called "Quilt Smart". It was so very easy to do. I finished my blocks to make the quilt top but haven't gotten it quilted as yet. I am such a procrastinater.
