I've started collecting 2" squares for a Postage Stamp Quilt. I've cut out 200 squares; swapped 1/2, so have 100 different squares. At least, this is a start, lol. I'm thinking when I have a few more cut, I want to start my blocks. I can't decide if I want to do just the squares or if I want to pair each square with muslin. What do you advise?
