I built the barn doors from scrap wood. I cut two pieces of 1/8" thick plywood measuring 4 3/16" wide by8 3/8" tall. I measured and scored 1/2" wide planks for each door on both sides. I cut, marred and applied strips of basswood to make the supports. Using the same technique as I had for the siding, I made fake nail holes.
I painted the doors to match the barn. Since the wood started as a different color, the barn doors are slightly off from the rest. They are also still wet. We'll see what they look like after drying.
I'll address the hardware next. These will be sliding doors.
