I ordered 4 yards of backing fabric from keepsake fabrics, but they only had 3 yards precuts plus a 1.5 yard. I decided to pass on the order. For this project (BHMQ-21, for me), I wanted a one piece backing. When I get the project completed I will need to decide then. I’m also eyeing a backing piece in my stash. So, so far I’m not buying fabric. My finished BHMQ top will be about 120” wide by 85-90” long. BTW, I like keepsake fabric company. It just didn’t work for me at this time. So I’m still on the wagon.
