This playing card box was made from a floor joist salvaged from a 150 year old house that was in the process of being renovated. While working on this project, another TechShop member identified this piece as Spruce, and from the small amount of discoloration caused by Spalting, it was most likely cut from a tree that was dead for some time.
That means this project may actually be the second time this piece of wood was reclaimed!
