Birmingham wool shops number 5. It is famous for its cotton production, like many of the textile manufacturing towns in the north of England. It is the most populous city in the UK, with only London being the biggest. With Wolverhampton. Coventry, Solihull and Tamworth neighbouring, it's the place to be for the knitting fraternity in the Midlands.
Birmingham is a city leading in the worldwide development in science and technology - not particularly an art related city but it's the population growth that makes it a bustling centre. It's markets are a great place to sell your crafting projects.
