Constructing the felt pieces.

Constructing the modules was straightforward. The 3d printed blocks act like registration pegs and held the felt in the correct position. I used UHU glue in a bottle with a small nozzle to construct it. The main issue was working out what went where. I printed out the laser plans and used them like a puzzle solution. 

I used fewer of the larger areas of felt as I needed less of them to create the height I wanted.  I worked on them all at the same time to ensure the profiles joined up.
