Tip: A wooden Mancala board makes a great sorting tray!

bit posh for me.... you can use plastic egg trays, egg cartons, ice cube trays, apple trays (the fruit), bits of double sided tape, whatever you like.some people draw a rough diagram on cardboard and then punch the screws in as they go along (updating the drawing too)

An even cheaper solution I learned from R/C modeling days is to use an egg carton. These can be found in 12 and 30-egg sizes, and the supply is practically limitless!

Another good use for the 30-egg size is as sound insulation on budget recording rooms. The irregular surface makes sound reflection off the walls virtually non-existing. Try it; works great!
