Hi Judith, I have not tried it but at the beginning of the month when someone mentioned it, I had to google it to find out what the process was.
I found one good you tube video by American Quilting titled Back Basted Applique that is 14 minutes long. It takes you thru the process.
That might help you. I love that you are open to learning new quilting techniques. Very inspirational.
I noticed that you also said books. It looks like Barbara Eikmeirer's book on back basting got a lot of good reviews on Amazon.
