Where to buy a small amount of hot-water-soluble PVA nonwoven fabric?

Hi all — I'm working on a small DIY/prototype project and I'm trying to find hot-water-soluble PVA nonwoven fabric (the kind that stays stable at room temperature and dissolves in hot water, \~90°C). It's similar to the water-soluble embroidery stabilizer some of you use, but I'm specifically after the nonwoven (cloth-like) version, ideally around 50-70 gsm so it's sturdy.

The problem: almost every supplier I find only sells huge wholesale quantities (hundreds to thousands of meters). I just need a small amount — a sample or a few meters — to test.

Does anyone:

\- Know where to buy this in small/retail quantities (US-based ideally)?

\- Use this material and have a source you trust?

\- Know a supplier that's good with small orders?

Any leads appreciated. Thanks!
