Try etsy.com, look under supplies. You should find some nice fabrics. Also, try Mood fabrics. Mood has beautiful fabrics. If I think of more - will let u know.

(Brain freeze)! Anna Maria Horner fabrics and purlsoho. They have beautiful fabrics! Purlsoho even has yarn. I hope this helps you!

Thanks, Butterfly. I live in Germany and not only the fabrics at stores are very expensive but they are very boring too.

@clabrazil: Hobbyschneiderin offers link lists to German fabric stores and a lot more interesting links. Look for Stoffanbieter.

For Germany - there ist a fabric-market of the netherlands that is "on tour": Stoffmarkt Holland they have great amount of cheap fabrics with good qualities...

Yes, the Stoffmarkt Holland is definitely worth it. I'm going there this Saturday. Too bad they only come 2-4 times a year though!
