Knitting is such a wonderful outlet for creativity and expressing yourself! You can choose from a myriad of knitting patterns and knitting styles, and as you get more experienced, you can start creating your own. It's a wonderful, open-ended process of exploring and expressing your taste and your ideas!
All you need is any old ball of wool, some knitting needles and either someone to give you an hour of their time to show you the basics or a fish about on Youtube for a good video. Everything you need to start will be for sale on your high street. No need for expensive equipment or huge amounts of training. Get the basics and make a start.
