I've never used sheets, Babs, but that's an excellent idea. Someone on here said they pick them up at Goodwill or other shops selling used items. If you hit a sale at housewares stores I'm sure it's pretty reasonable to go that route. I'm very lucky to have a fabric warehouse about 20 min. from my house in California. They have tons and tons of fabrics for under $3/yard. That's usually what I'm using for backs. It's pretty simple to piece backs and if using prints the seams are barely noticeable after quilting. Besides, who spends much time looking at the back? I very rarely use solids on the back of a quilt. I like designs so much. That's what I get for backing almost 100% of the time. I haven't used blocks yet but I think that's so fun to do that. Babs, I'm sure you and I would've been good buddies back in the 70's! I was definitely in hippie mode but only up to a certain point. Hahahaha!!!
