Mine was from "Less Than Traditional" at Quilter's Haven. by "Charlie". You can get different size circles and rulers that help you place the "square" in exactly the right place. I love the look. Ann
A friend of mine made one with denim for the backing. She used a salad plate for the templet.
I made 6 lap quilts and used a plate as my circle template, so easy to cut around with the rotary cutter. You can use any size dish/plate to make them.
