Pellon 725P Heavy Duty Wonder Under

Pellon 725 Heavy-Duty Wonder-Under is a powerful, paper-backed fusible web that transforms any fabric into a fusible one—with twice the adhesive strength of the original Wonder-Under®. Designed for demanding applications, it bonds fabric to fabric or to porous surfaces like wood and cardboard, making it perfect for denim, canvas, and other heavyweight materials. This lightweight, single-sided fusible web has no grain, so it can be cut and applied in any direction for maximum versatility. Made from acid-free 100% polyester, it’s safe for machine washing or dry cleaning—just follow the care instructions for your fabric and skip the fabric softener. When your project needs extra holding power, Wonder-Under 725 delivers.
