Pot scrubber thread

I continue to use (and wear out) those wonderful pot scrubbers that I talked about before. I've been looking and looking for the thread that is needed to make them. No luck. #2MIL thought it might be something like "teflon thread," but the only thing I could find in that vein was used for plumbing and is really a tape (as it turns out, pipes have threads).

Today I think I found it. This pot scrubber looks like a close relative to the ones that I am using, and the supply list calls for "nylon plastic canvas yarn." Ima go get some the first chance I get and hand it over to Big Kid Cousin. Let's see what the girl can do. ^.^
