Tartan, I have lots of the sports fabric plus some in red that I have cut out. (For those times when I want to do aimless sewing, ie: straight lines! LOL!) I also have cars and dinosaurs. I think at one time I had 6 yards of each and am whittling it down. I make sure that I send duplicates to different places.
Donation quilts are so much fun cause they take little time and are generally easy to sew. One can be done in a day.
