Frequently Asked Questions

What does Soft and Stable do that interfacing can't?

Stand up — fusible interfacings stiffen fabric but don't give it body; the 3/8" foam gives bags dimensional structure, so a finished tote holds its shape empty on a table. It's the difference between homemade and boutique.

Does it really sew on a home machine?

Yes — that's the engineering point. Standard needle, normal stitch length; it feeds without the compression and bunching craft foam causes.

White or black?

By exterior fabric: white behind lights and mediums, black behind darks where white foam would shadow through at seams and edges.

Why the 72" x 58" cut?

Per-bag economics — pattern-cutting several bags from one large piece beats buying per-project cuts, the natural format for bag makers in any volume.

How does it survive washing?

The polyester foam holds its structure through machine cycles — everyday-use bags come out of the wash still standing, which is what separates it from cardboard-stiffened construction.
