Whenever I have spent too much time in front of a computer, it's a healthy exercise to create something with my hands. Here is a picture from my most recent project:
The reading corner in front of the fireplace is now surrounded by a new bookshelf. I have built it from scratch, using cheap Douglas-fir wood, which was originally intended for the floor of our veranda. I was surprised myself that it took me less than three days from plan to completion and the work was great fun.
