Isn't that cotton fabric? I know Walmart sells them pretty cheap. It's what 5 - 6 yards on each side depending on what size you get?
The poly batting can be used to make body pillows or regular pillows, pet bed stuffing, toys etc.
I have two that I really like the colors of the fabric, don't use them much and would love to take them apart and resew into things like mug rugs, table runners for spring etc.
