This stunning set of 40 vintage and newer cotton quilt squares is made up on a wonderful selection of coordinated fabric that wil set off any quilt nicely. There are some very tiny prints among these beauties including vintage feedsack fabric from the 30s and 40s. There might be one or two in the group that aren't 100% cotton according to the quilting club that we purchased these lots from. We were informed that 99% off all of what they offered at the auction were 100% cotton.
