The strips for the cabinet doors were rip from a piece of pine and glued to the doors. The Barn door strips were 1/4" x 4" discontinued rough wood from Home Depot. I purchased a bundle of it with no particular project in mind.
It was a slightly similar design on pinterest just a picture, but no plans or design. I drew up the plans and built a material list because I needed to be able to disassemble and reassemble when the bed was delivered. I add the headboard from the strap pieces of wood.
