Description
Pellon 725 Heavy-Duty Wonder-Under is a paper-backed fusible web with twice the adhesive of original Wonder-Under. It turns any fabric into a fusible fabric and bonds fabric to fabric or to another porous surface such as wood or cardboard. Reach for it on denim, canvas and other heavy fabrics, and whenever an appliqué or no-sew project needs extra holding power. It has no grain, so it can be cut and applied in any direction.
The 17" x 10 yard bolt is the economical format for anyone who does a lot of appliqué or fabric-covered craft projects. The finished item can be washed or dry-cleaned according to the fabric's care requirements. For quilting-weight cottons and appliqué you plan to stitch through, regular Pellon 805 Wonder-Under is lighter and easier on the needle; for sheers and light fabrics where paper-backed web would show, Pellon 800 Clear-Fuse is the clear option.
