I found a website that (at no charge) converts a picture into squares. It works pretty well for graphing out quilts. I downloaded a jpg of an image of the popular number 12 for the Seattle Seahawks football team to create a quilt for my BF. Cut the squares into 2 1/2" squares, added a few borders and it turned out great.
