I have prayer garden. I haven't done the entire quilt but did do one set of blocks for a pillow. I'm trying to remember how wide I cut the strips for the folded fabric technique. I'm thinking 2" or 2.5" wide. My suggestion would be to try one of the smaller blocks using scrap fabric - then you'll know what you need to cut them. They stitch out quickly, so it wouldn't take long to do a test. You probably can call AGD and ask them also. Good luck! I love Prayer Garden and hope to get time soon to do the entire quilt.
