Heddy's has gorgeous fabric and pretty much anything you nee to make some sort of garment or costume. However, I find the place to be ridiculously overpriced. The first time I went in, I thought the prices marked on their rolls of fabric HAD to be for the whole roll because the prices for their spandex fabrics are marked for over 20 bucks PER YARD. Are you serious? I know I can't really compare this place to the fashion district in L.A. where I get the same fabric for $5 a yard (at most), but even at Jo-Anns or Hancock Fabric, I can get some of the same material for around $8/yard with their weekly coupons.
This place is definitely nice to browse around because they have very nice fabric, but I think the only thing I'd ever buy here would be their remnant pieces.
