how much fabric can i order?

Check out this fabric store:

They have some of the same stuff that repro depot carries but then there are lots of other very cool things that repro depot doesn't have. Also it looks like just about everything is roughly 9 bucks a yard. That is a sweet deal in my book.

Some faves from purl soho:
