HeatnBond Soft Stretch Ultra — Iron-On Web Adhesive (for Knits & Stretch)

HeatnBond Soft Stretch Ultra — strong, permanent iron-on for knits & stretch
Soft hand, low bulk • keeps fabric stretch & drape
No-sew required (sew-through optional; won’t gum needles)
 
Keep the stretch, lose the pins. HeatnBond Soft Stretch Ultra is a lightweight, iron-on web adhesive that bonds knits and stretch wovens without adding bulk—so your fabric still moves and feels soft after fusing. The Ultra formula creates a strong, permanent bond (no-sew required). You can stitch through it by hand or machine if you want extra security; just use a longer stitch length to avoid perforating the bond.

Pre-wash fabrics (no softener). Test on a scrap.
Place web on wrong side of your fabric (paper side up).
Press (no steam) ~5 seconds per area to fuse to the fabric; let cool, peel paper.
Position on project, press with steam ~20 seconds per section for final bond.
Optional: stitch around edges (use a longer stitch on knits).
Pro tip: Lift-and-press—don’t slide the iron. Use a press cloth for the cleanest fuse.
