I learnt amigurumi and crochet from YouTube too - you'd be amazed at the handy videos on there! I made my first pattern after about 1 month of ami making - it was just a simple pill shape that I sewed eyes onto and called it Zak The Prozac lol! Start off small, then things will just progress from there. Once you get the basics like a ball and tubes you are half way there
Have fun with it too!! That's what it's all about!
