Ecology cloth
Sauders Fabric store 681 S Muddy Creek Rd Denver, PA 17517 (717) 336-2664 used to have it. I just contacted them and they are out of it. They would have to order it if I wanted. It sells for $3.99. They used to give you 10% if you spend $100 or more or bought the whole bolt. Last few years I have been buying it from "Goods Store" in Pa. They have a chain, I am not sure which one I contacted but if one sells it the rest should do too. (717) 354-4026, (717) 786-9028, (717) 949-2663, (717) 733-7356 - ask for fabric department and ask for ecology cloth. Last time (few years ago) I paid $3.49 a yard. I will have to call them soon myself, I am running out of ecology cloth.
