We have been dyeing fabric since the '80s and know what material dyes the best. We always had trouble finding sheet material without sizing or treated with chemicals.  These blank white tapestries are sweet and dye well. For the best results, we do suggest washing with Calsolene Oil before dyeing.  We even included loops on the corners for that extra finished look. Tie-dyeing a tapestry is great for fun and profit. Check out our blank white bandanas, too.  Pro-dyers check the quantity discounts.  Works well with Fabric Spray Dye as well as fiber reactive Procion dyes.
