Go shopping there have to be some good upholstery shops there for sure and they usually have fabrics too. Or google boucle upholstery fabric

Google can help.

Ya I've tried both of these steps. Unfortunately the Etsy fabrics are all more of that "fuzzy blanket" texture and I'm looking for more of a weave with pile. The stores I've been to either don't have performance boucles or they are ~$90.

You might try West Elm. I just got swatches from them (tweed), but I think they sell boucle, too. Scroll down for various types of fabrics:

They don’t give rub count, so I’d ask about that.

The swatches are free, up to 15, and come within days. I got five for my project and really like how they look.
