I start all of my projects at the computer.
I make a detailed drawing right down to joinery using Sketchup.
This has save me several errors over the years as I have all ready built it before cutting any wood.
Create my cut-list and material list from the drawing
Pickup any required materials
Rough mill my stock and let it sit for at least an week, the bring the parts down to final dimension
Complete the project
Post the design to my website
