Hello,
Do most people usually buy the actual yarn stated in the pattern, or is it very common to substitute? When i learnt to knit i was only making clothes for my dolls so have never followed a pattern or anything before. (They weren't very professional items but i was 10 so its allowed)
Also, i've read mixed reports on using polyester yarn, are natural fibres much nicer to work with or does it not make a huge amount of difference?
