Hi all! I'm making a window seat cushion for a personal friend and during our trip to Joann's yesterday, I realized it was going to cost around $120 for the amount of foam we need! (3 inches thick and 91inches x16.5inches) I was in shock that just the foam would cost that much! I decided to not buy and do some online shopping to see if I could find it cheaper elsewhere. THe only other place I've been able to find it thus far is on a website called buyfoam.com. I can get it custom cut directly from them. The price: $50! SO much cheaper. But, I'm hesitant and would like some opinions suggestions on where you buy your foam, brands you like, etc.
