Frequently Asked Questions

What does SF101 actually do to fabric?

It adds body and stability while keeping a soft, natural hand — structure that still moves with the fabric, not the board-like stiffness of heavier interfacings.

Why is a woven cotton interfacing better for quilters?

Because it behaves like quilting cotton itself — it presses, sews, and washes the same way, and never introduces a plastic feel into the finished project.

Can I use it on knits?

No — SF101 is woven and doesn't stretch. For knits, use Pellon EK130 Easy-Knit, which stretches with the fabric.

How do I apply it correctly?

Rough (adhesive) side against the wrong side of the fabric, dry iron on cotton setting, press 10–15 seconds per section without sliding, then let it cool before handling.

Is the bond permanent through washing?

Yes — properly fused, it survives repeated machine washing and dry cleaning without delaminating.
