After building myself a Christmas Tree shelf for 2019, friends and family wanted me to build them one for 2020.
Three people wanted a smaller tree so I scaled down the plans and used 1x4's ripped to 3 inches.
I also included cup hooks (3 or 4) and an aluminum french cleat hanger I found on Amazon for about $5 each when you buy three.
For a top coat I used spray lacquer on one of white-washed trees and clear Krylon on another. No top coat was applied to the other trees.
