Fabric shopping

I just went on a blitzkrieg of fabric shopping for some batiks for a project I have in mind.  Besides the local quilt shops, I have a couple of online places that I really like a lot for fabric shopping.  One is called Thousands of Bolts - it's amazing how much stuff they have (like thousands of bolts! LOL!) and the prices are incredible - about $4 a yard for what you'd pay in a quilt shop.  So I've bought tons of stuff from them.  For the batiks that I just bought, I went to Old Country Store Fabrics.  They're very good prices, too (about $7-$8 per yard) and have a bajillion batiks to choose from.  I'm trying to build up my stash of batiks at the moment, since it is somewhat lacking.  I have quite a bit of 1800s/Civil War repros, and 1930s repros, but seems like my tastes and interests wanders at times.  I've got enough fabric at the moment to literally make about 100 quilts probably, so when does it ever become "enough"?  Probably never at the rate I'm going.  :)
