Pellon Thermolam Plus Sew-In Fleece Stabilizer 45in x 10 Yards

The Pellon Thermolam Plus Sew-In Fleece Stabilizer — 45" x 10 Yards is a thick, lofty sew-in (non-fusible) fleece batting substitute. Unlike fusible fleece, Thermolam Plus is sewn into bag and accessory projects through seam allowances and quilting — ideal for any project where heat cannot be used to fuse the stabilizer, such as vinyl-exterior bags or other heat-sensitive materials.

Frequently Asked Questions

Why choose sew-in over fusible fleece?

For heat-sensitive exterior fabrics (vinyl, faux leather, PUL) where an iron cannot be used, sew-in Thermolam Plus is the appropriate choice. It provides the same padded loft as fusible fleece without requiring heat application.

Is Thermolam Plus the same as Pellon 820 Fusible Fleece?

Thermolam Plus is the sew-in version; 820 is the fusible version. Both provide similar padded loft — the difference is application method only.

How is Thermolam Plus used in bags?

Cut to shape, layer against the wrong side of the bag exterior panel, and sew together along all seam allowances. The seam allowances trap the Thermolam Plus in place; no fusing required.

Can Thermolam Plus be quilted through?

Yes — machine quilting through Thermolam Plus and bag exterior creates a padded, quilted bag panel.

Is Thermolam Plus machine washable in finished projects?

Yes — check care instructions for the complete project. Thermolam Plus itself is machine washable on gentle cycle.
