The most important thing I learnt was patience - I wanted to cut everything and then grind and then fit but after the first few pieces I finally realised that I needed to cut and fit a maximum of three pieces at a time and it was best if they were consecutive pieces not the ones that I thought were most difficult or entertaining to cut. Mostly I learnt what fun you could have and how much building a lamp resembled building a puzzle but it was a puzzle that I could make endless variations of much more entertaining.
