Through Pinterest I found this Michelle pattern and thought I had to make it. It was relatively easy to do. The case fits my Canon Ixus perfectly. Only issue I had was that I quickly realised how rusty my machining skills were, and I'm not happy with myself! I'll just have to do lots more practice! The pattern is available here:
