I've had success with stitchzone.com, however as I'm in Canada the cost is a little bit much for me with shipping.. so we've resorted to finding a local place who orders from different places (like amercian apparal) and stitches our crest / letters onto the clothes. most of the greek organizations here use them
Hey,
I'm not in a local, but www.greekave.com has some really nice stuff and it's pretty cheap. I'd suggest signing up for the mailing list and waiting for the really good sales.
