I need 1/4 in foam fast!?

Question:Hey can anyone point me in the right direction for some chain stores that would carry foam in this thickness. The thinnest foam that Jo-anns crafts carries is 1/2 inch and that's just to thick for what I need it for. I don't have enough time to order from the internett and since I don't need a large amount (only about a small square) I was hopeing that someone may have seen some in just a regular store.

Answers:
Hamilton Fabrics, Home Depot, Lowes (Yes Hardware stores carry very thin strips of foam as well), also try Hobby Lobby or any other crafts stores they carry it as well.
Good luck.
