fusible web

Most items fused with fusible web can be machine washed and dried after sewing, but follow the product’s care instructions. Product descriptions here mention machine wash warm and tumble dry low or dry clean as possible care options. When in doubt, check the specific item label or manufacturer guidance before laundering.

A "pressure sensitive" or "temporary hold" double-stick fusible web holds appliqué and background pieces in place and lets you reposition them by applying pressure. The hold is temporary until you permanently fuse the pieces using heat (for example, an iron) to create the final bond.

Pressing technique changes the bond stiffness: a light steam press yields a softer, more flexible bond, while repeating steam passes with increased pressure produces a firmer, more rigid finish. In short, amount of steam and pressure together control softness versus firmness.

Some fusible webs will bond fabric to porous non‑fabric surfaces. The listings mention paper, cardboard, and wood specifically, and note that regular‑weight web is used with paper, cardboard, wood and even glass beads.

Most items list polyester fiber (including 100% polyester). Some interfacings are a polyester/rayon blend (90% polyester, 10% rayon), and a few descriptions note foam or polyfoam construction.

These interfacings are suited to light‑ to midweight wovens and knits. Examples listed include challis, chambray, jersey, broadcloth, linen, sweater knits, machine knits, wool, flannel, and gabardine; some interfacings are specified for T‑shirt materials.
