What is the difference between FF79F2 (two-sided) and FF78F1 (one-sided) Flex-Foam?

FF79F2 has fusible coating on both sides so it bonds to both the outer fabric and lining simultaneously. FF78F1 has fusible on one side only and is sewn into the project on the second side. Use FF79F2 when you want a fully fused, sewn-free construction; use FF78F1 when you prefer to sew the stabilizer in.

How do I apply two-sided fusible foam to bag panels?

Cut the foam to size, place between the outer fabric and lining (both wrong sides facing the foam), and press firmly with a hot iron following Pellon’s instructions. The foam bonds to both layers simultaneously. Use a pressing cloth to protect delicate fabrics.

Will two-sided fusible foam show through the outer fabric?

No — the foam stabilizer is sandwiched between layers and is not visible from the outside of the finished bag. The outer fabric’s appearance is unaffected.

Can I quilt through two-sided Flex-Foam?

Yes — after fusing, the sandwich can be quilted on a domestic machine. Many bag makers quilt decorative lines through the fused layers before constructing the bag, creating a structured, quilted exterior.

Is Flex-Foam machine washable after fusing?

Yes — once fused, the Pellon Flex-Foam stabilizer is designed to withstand machine washing on a gentle cycle and tumble drying on low heat.
