I love amigurumi! I find it a little hard on my weak-ass hands but that goes for all of crochet in general. As for the complexity of this particular branch of crochet, it's not very difficult once you get the hang of it. All you need to know is how to single crochet, increase and decrease. I strongly believe if you know these simple stitches, you can make these lovely patterns. Click on the pictures below to go to the original source of each pattern.
