All of the wood used in the project was milled in our yard, from trees on our land. The 4x4 uprights are poplar, and the rest is spruce, all originating within 500m of our house. The wood was sticker stacked for 2 years prior to planing down to the required size( last picture shows a not yet planed 1X6.)
Was a great project we have had many compliments on as it is the bed in our guest bedroom and has been used plenty during the Christmas season.
My only change up was using 1x6 for the side rails instead of 1x10 due to availability. Turned out amazing!
