Imagine a sheet or strip of gauze cloth on a table. Imagine you have a
block of wood with a plastic material that has cuts in it like fish
scales, all going one way. You could slide the block one way on the gauze
and the fish scales would grab the gauze and move it along the table.
When you slide the block the other way, the fish scales wouldn't grab and
the block would just slide across the gauze.

Kind of a one-way clutch for gauze. I heard rumor that 3M made something
like this but can't find it. Any experience or ideas?

This sounds a little like the gadgets made for removing lint from clothes.
They have little loops, like nylon monofilament line, and they all lie in
one direction.

When you push this "brush" in one direction, it digs into fabric a bit and
picks up lint. When you push it in the other direction, it just slides over.

You can find them in your supermarket or thread shop, for around $3 each.
The material may be something that's commercially available in quantities.
