What fun it has been! Many years ago I did a carpentry course in which I learned how to use a few different saws and how to build simple structures and the like.

Over the past few years, I've also been dabbling with woodworking - one more thing in a list of hobbies that I've learned to totally enjoy. Here's a photo of some of the things I've created so far.
