craftgrrl | Places To Buy Fabric Online??

Ok, I don't live near any fabric stores, only Walmart. I did however go to two different Jo-Ann's out of town last month. I have been looking for knit fabrics in good prints. I didn't find much, mostly solid colors or really kiddie prints. Plus they were $7.00 and up a yard.

So my question is... I see on eBay all these girls making these clothes with neon striped fabrics, cool floral prints (not the old lady ones, that I keep finding), skull fabric, etc. I just want to make myself some t-shirts, but I don't want to have to shell out $50.00 to make one, or I'll just buy one!

So where the hell do you find all these cool knit fabrics??? Can anyone tell me?? Please?? I've looked everywhere online.
