Fabric sourcing in London

We got to go fabric shopping London which was really fun, i didnt enjoy the early start so much though. Ive been fabric sourcing in london couple of times before with college and on my own because in live in Woking which is only 30 minutes away on the train which is lucky because i knew my way around quite well. The fabric stores around Soho are my favorite around London but unfortunately seem to be the most expensive, this is why i find it a good place to come and get samples. I hate asking for sample because each store reacts differently but most were friendly and gave me the fabrics that i liked.
