On the internet:
I buy from these internet shops because of the fast delivery, good price and helpfull advice:
Purple Linda Crafts for Aida crochet thread and Clover Soft Touch crochet hooks.
Love Knitting for Rowan, Sublime and Knit Pro crochet hooks, but they have lots of other brands as well.
Tudor Williams in New Malden if I need Stylecraft but don’t want to wait for the postman. I also bought the Sirdar Snugly Baby Bamboo that I used to jazz up my Boden skirt, on sale here.
John Lewis in Kingston if I need Rowan but don’t want to wait for the postman.
