I just made my first one a couple of weeks ago and it was not nearly as hard as I expected it to be. My friend Marjorie blogged about hers
http://b-quilts.com/blog/?paged=2 and I just followed her instructions. After you read the first post, click on "newer posts" at the top of the page and it will give you more information. She recommends French fuse, which is also what I used to stabilize the shirts and it worked great. Marjorie now has mine to quilt and when it returns home I will post a picture.
