Clear - 20in x 1yds. Sulky Super Solvy stabilizer is the perfect temporary stabilizer and transfer agent that dissolves in water. Twice as thick, heavy and strong as the Original Sulky Solvy. Use as a design template, as a pattern guide and as a stitch support. Super Solvy is the perfect choice when you need a heavier Solvy that will withstand a lot more stitching and tugging. Ideal when you do not want any stabilizer to show on the top or bottom. All Sulky stabilizers are acid and lead free!
