I would really like to make a scarf's for my friends/family and myself but I have no clue about what size knitting needle to use could anyone tell me the best size? Also I'm not to sure what wool/yarn would be best to use I would like the scarf to be soft but warm, and could any one recommend a good webiste to buy this from in bulk? Every store I have been in says the size needle depends on what wool you are using and that the wool depends on what pattern and they can't just give me a helpful answer as I don't need to use a pattern to make a scarf (lol) thanks you for your any help given xx:)xx
