I love this back fabric. It is actually a sportswear cotton, so a little heavier than normal, but it quilted up just fine. I had purchased it because I loved the owls and the colors...thought I might make pillows out of it, but it fit this quilt just perfectly. It's 60" wide, so I didn't have to piece it either. I used a sportswear cotton on the Jigsaw Puzzle quilt last year because I loved the circular pattern for that quilt, so I knew it would quilt up just fine. It makes the quilt a little heavier, but should wash up just fine.
I am heading up to load another one soon. My stitching group meets tonight, we are all bringing our Round Robin quilts...can't wait to see what everyone did to finish them up. I will take pictures!
