I am getting ready for baby and am looking for PUL fabric pieces that are large enough to make a diaper cover... As of yet I haven't found any locally. If you have some you don't need or know a store where you can get it on discount... think of me. Thank you. Edited to add: PUL: stands for Poly Urethane Laminate. It is simply a knit or woven fabric that has been laminated with polyurethane to make it waterproof.
