In the old days I probably would have bought them all, and these days I should probably just experiment; however, I might allow myself one book. I've seen the basic tutes online.

I personally would save the book money for something that I couldn't find the tutes online. The tube quilting theory isn't that difficult, and some creative searching here will give tons of pictures!

You can go to you tube and type in tube quilting.Missouri quilt company has a few video on tube quilting.
