Since I make kids quilts for foster kids in my county I don't worry much about the backings. I make scrappy quilts so I am sure to get at least some colors the kid will like. I have been buying backings at Hobby Lobby. They are a bit pricey. I buy 2yards and can get two backings and some left for piecing. I will have to start piecing backings as I pay for everything I use. I make quilts at least 43" x 57" or 58". With inflation being what it is I must use what I have. My aim is for them to be nice looking on one side and to be warm.
