Hello Butterflywing
I do not know if you have solved the problem to finding out how the Betty Cotton theory quilting is done. I am new to this website and also a qualified instructor of Betty's. For your first project I would not recommend flannel fabric. Each block is quilted leaving one inch around the block free of batting. It is a good idea to use Betty's batting as you can steam it with an iron and it adheres to the fabric. Quilting is easy then without pins. I did post one picture of the start of a placemat and I can post more too. But I will leave this note for now as I do not know if you already worked out how it is done. Look forward to hearing from you.
