What have you done to challenge yourself?
Lately it seems that all the things I've made have been things that I "had to" make and haven't been particularly challenging for my skill (that's not to say that they haven't been fun!). I want to plan a project that's going to push me a little more. What projects have you all done to learn or improve your skills? I want to hear your stories. I'm hoping that if I hear what others have done to challenge themselves it will inspire me. Actually, I'm sure it will!
