Yeah.. it's in the sewing/crafts section.. pillow fill stuff.. actually called "polly fill" on the bag.. makes it easy to find polly fill ;)

pretty cheap too.. I think I paid like $3 for 20oz.. someone said about 16 - 18 oz per cubic foot..??

Polyfill is cheap...I got a 5lb box for like $10. (Fiberglass is itchy and pricy)
