Well, I've finally done it! I've designed all my Star Wars amigurumi to my satisfaction, written up the patterns, photographed them, put the patterns together and put them all on Etsy!
Some of them took longer than others to perfect. I wasn't sure if C-3PO would work, but I was happy with him straight away. Vader, on the other hand, I just couldn't get right. His head, his face mask, how much detail to give him. Since his costume is almost entirely black it's very hard to define any details. I made him several times with a flat triangular mask and it wasn't until I made it more three-dimensional that I was satisfied.
The Ewok was tough, too. I made him in a completely different way with his hood as part of his head, which I thought I liked, but when I came to write the pattern up it just seemed too unnecessarily complicated. since I'd just been making my crocheted cork knights I realised I could use a similar technique to make a simple separate hood, which I much preferred.
Apart from fine-tuning his height, I liked my Chewbacca, which I made with an alpaca mix yarn then brushed, but I realised that finding that particular type of yarn might be difficult. So I also made him using a normal smooth acrylic yarn that had various different browns in it and which brushed up just as nicely with a wire pet brush.
Anyway, I'm very happy with the finished patterns. If they prove to be popular I'll have to work on some more characters - I think I'll do Boba Fett and Obi Wan next.

Not all these patterns are available for sale now, as they are going to be included in a new Star Wars crochet book, due to be published Spring 2015.
