I sell polyester but my stock is very low. I can tell you from experience that finding suitable uncoated polyester is hard! As far as I know there are only two of us that sell polyester and my stock is almost gone.

I have been searching and talking to mills and distributors around the US and Canada trying to find a new supplier(s). I have had places that would be happy to make what ever I want but their minimum runs are huge and the market is small. So it's a matter of find something currently made that will work and that is like a needle in a haystack.

I have one promising sample and hoping by summer to have at least a couple of new choices in polyester fabrics. But right now I would be happy to just have one!
