Carin and Carol over at Margaret's Hope Chest. They are looking to gather children's quilts for their Prison Ministry this summer. You can read more about the quilt drive here. I change the pattern a wee bit since I had a stash of 6.5 inch cut novelty squares.
I first saw the pattern at Katie's Swim, Bike, Quilt blog. The original pattern is called Storytime Squares by Rae and can be found here.
