Pellon FF78F1 One-Sided Fusible Flex-Foam Stabilizer 20in x 10 Yards

The Pellon FF78F1 One-Sided Fusible Flex-Foam Stabilizer — 20" x 10 Yards Bolt is a specialty foam stabilizer with a heat-activated fusible adhesive on one side. Flex-Foam is thicker and more structured than fleece stabilizers — it adds significant body and rigidity to bags, totes, and accessories — but remains flexible enough to create bags that bend and close naturally.

Frequently Asked Questions

What is the difference between Flex-Foam and Fusible Fleece (987F)?

Fusible Fleece (987F) adds padding and moderate body. Flex-Foam (FF78F1) is thicker and adds significantly more structure — it creates bags that hold their shape firmly. The “flex” in the name means it remains flexible despite its thickness, so bags can still open and close naturally. Use Flex-Foam when you want a stiffer, more structured bag than fleece can provide.

Is this product similar to Soft and Stable foam?

Both are foam stabilizers for structured bags. The specific thickness, density, and fusibility differ between products. Pellon Flex-Foam is one-sided fusible, making application straightforward. Soft and Stable is sew-in. Compare based on your specific project’s structure requirements.

How do I apply one-sided Flex-Foam?

Place the rough (adhesive) side against the wrong side of your bag exterior fabric. Press with a dry iron at a medium-high temperature for 10–15 seconds per section without sliding the iron. Test on a scrap first. Once fused, the foam and fabric move as a single unit through construction.

Can Flex-Foam be quilted through?

Yes — like other foam stabilizers, Flex-Foam can be quilted through to create a structured, flat-quilted surface before bag construction. The foam provides resistance that creates clear, defined quilting channels.

Is Flex-Foam washable?

Check the specific Pellon Flex-Foam care instructions. Most foam stabilizers are machine washable on gentle cycle; high heat should be avoided to preserve the foam structure.
