This pattern book has three sizes of tray letters. You can use these letters for desk name signs or inspirational words. Wherever you need a sign these letters can come in handy.
The letters can be cut from any thickness of wood. You just match the slot in the tray to match the letters. In the above example, I cut the letters from 1/2" thick walnut so the slot needed to be 1/2" wide.
In this example, the letters were 1/8" thick
You can use any method of cutting the slot that you like. I used the table saw and moved the fence until the slot was a snug fit for the letters.
