Pellon FF79F2 Two-Sided Fusible Flex-Foam Stabilizer 20in x 10 Yards

The Pellon FF79F2 Two-Sided Fusible Flex-Foam Stabilizer — 20" x 10 Yards is a thick foam stabilizer with heat-activated fusible adhesive on both sides. Unlike the one-sided FF78F1, the two-sided version allows you to fuse both the exterior fabric and the lining to the foam in a single pressing step, creating a fully bonded bag structure without basting or stitching the foam to fabric layers separately.

Frequently Asked Questions

What is the advantage of two-sided fusible over one-sided?

Two-sided fusible allows you to fuse the foam to both fabric layers (exterior and lining) simultaneously in one pressing step. This creates a more integrated, stable bag structure than one-sided fusing, and eliminates the need to separately baste the non-fused side. For bag projects where precision alignment matters, two-sided is a significant workflow improvement.

Is FF79F2 the same thickness as FF78F1?

Both are thick foam stabilizers, but the two-sided version may have slightly different specifications due to the double-sided adhesive application. Check the Pellon product specifications for exact thickness comparison.

How do I apply two-sided fusible foam?

Position the foam on the wrong side of the exterior fabric. Press with a dry iron to fuse one side. Then position the lining fabric on the unfused side and press again to complete the bond. Work in sections with a slow, even pressing motion. Test temperature on a scrap first.

Can the two-sided foam be quilted through?

Yes — the fused foam and fabric layers can be quilted together before bag construction for added design interest and structure reinforcement.

Is FF79F2 washable?

Check Pellon’s specific care instructions. Most Pellon foam stabilizers tolerate gentle machine washing. Avoid high-heat drying which can compress or damage the foam structure.
