This has been a great topic. Generally, I enjoy math, geometry, and finding easier ways with which to do something. However, my enthusiasm is not necessarily your enthusiasm. With lots of books on my shelves and the Internet resources, I am able to really have fun perfecting my assembly methods. One important factor for me is that the method be fun and relaxing to me! Secondly, I want to use the material without much waste. Those two things make exploring different methods a challenge which is rewarding on many levels.
