Madeira's Avalon Wash Away Film Stabilizer prevents stitching from sinking and disappearing into the nap of the fabric. It's stretchable and ideal for delicate fabrics since they won't lose shape when embroidering or sewing on them. You can use the film on velvet, knits, silk, organza, netting, and more. Use it as a backing for buttonholes, to transfer quilt patterns, or for sandwiching or pizza techniques. Each roll of Madeira Wash Away Film Stabilizer measures 12" by 11 yards, is water-soluble, and transparent.
