There are lots of places. But you need to be more specific with the type of material you're looking for. Knit? Woven? What's it for?, etc.

Start out by looking at fabrics.com - they have pretty good prices and a lot of times they have some nice designer fabrics.

I'm a fabric addict, so if you put more information on what you're looking for, I'll come check and see if I can help better.

Patterns are available through companies like Burda, Vogue, Simplicity, and Butterick. If you're a beginning seamstress, it's easier to go by the pattern instruction which will tell you which fabrics you need and how much for a particular pattern. Look up fabric stores in the phone book. People there are usually helpful if you need something like "lightweight faille" or "wool crepe"

You need to go to a fabric store. You'll find mounds of diffrent materials there, some even with prints, but be careful because some are VERY expensive.

Check the prices first.

Ususally you'll find a fabric stall on your local market, They should have what you want, or maybe take a day trip to Birmingham, Leicester, London MK, Or if your up north try Manchester, Bury Market or another city .,.

You can buy fairtrade and organic cotton material from Gossypium http://www.gossypium.co.uk/hometextiles/fabrics/me...

There are some shops selling fabric stocks, you can get good deals and you will find a good variety, good luck!
