John Flynn's method is very good, However, one bit of warning, if you are intimidated about piecing bias squares,his method is one gigantic bias seam! Good Luck!

I've used John Flynn's pieced backs many time. I really like it because the seam on the back does not interfere with any seams on the top.

You just have to be careful not to stretch it. I have used flannel and it works out fine.

I have read that if you have to piece the back, you can use blocks - this add beauty.But, if you don't want to do that, cut it on the diagonal.

Very interesting ideas!

Like this idea.

I agree. Don't understand the formula. Also need to see a picture or video. Would love to do my quilt backing this way. Guess I could figure it out.
