Natural cork fabric, perfect for sewing on a home sewing machine! Great for bags and wallets. This is for the Natural Cork in Black color with Silver. The real cork is backed with a thin layer of fabric (the thin layer of backing fabric is a cotton/poly blend). Available in two different sizes: 18″ x 27″ and 18″ x 54″. Cork fabric is a natural cork material harvested from the cork oak tree in Portugal. It is bonded to a cotton/polyester blend fabric. The cork has UV protectant and Scotch Guard applied by the manufacturer. Try to avoid using cork for sharp corners or small, tight folds with several layers (like a small strap tab) – due to its natural properties, cork may produce small, superficial cracks. As it is a natural substrate, it may show some wear over time. I recommend a test sew with a small scrap to check your tension and stitch length. While we have tested the cork in a water bath for an hour and not found the colors to run or rub off on a white towel, you may prefer to do your own test. The cork fabric is dyed in lots, like yarn or solid-colored fabric is, and we unfortunately cannot guarantee that the cork that was purchased from us in the past is the exact same shade. Please purchase enough fabric to complete your project. To clean your finished cork project, please use a cloth dampened with water (optional: you can also use a mild, diluted soap) to wipe down the bag or pouch. Cork fabric reflects its tree origins. It has divets and small cracks. Like knots in wood, these natural deviations add to the beauty and are the reasons why a bag made with cork is so unique and sought after.
