We are temporarily replacing Roc-lon's Avalon 200 & 156 thread count muslins with Oeko-Tex's 100% cotton unbleached muslin. Use this 100% unbleached cotton muslin for printing, dyeing or draping. The lower 144 thread count has no finish making this fabric softer, easy to drape, smooth and easy to manipulate. Machine wash cold, tumble dry low heat and cool iron.
