If it is the Cincinnati Bengals, I have a large piece I could send you--it's leftover from a quilt I did and my DH is a Yankee, Knicks, Rangers, Jets fan.
also, do a search online to see if you can find somewhere with yardage instead of fat quarters. And, finally, you can always print the fabric on your own if you only want a few squares. You can buy fabric that is prepared already for an inkjet or you can buy bubble=jet=set. Also, maybe on this site? Someone printed a recipe for homemade (and therefore less expensive) bubble-jet-set.
