I found a tangle challenge thing on this amazing blog, Tickled to Tangle, and I thought that it might be a good thing to get me going. So here's my interpretation so far. I haven't limited myself to the 5 patterns beginning with C that the challenge required, but I have only used C patterns. I need to finish the big centre portion (which is a particularly tricky pattern) and do all my shading etc and it will be done!
I'll be honest, a lot of this could've ben done much neater and more precise, but hey, I'm still learning!
