Create the wood tree base using the barn wood cut into the following lengths:

• 10.25, 13.25, 16.5, 19.25, 28"   
• Use two 1-inch nails to attach the slats to the base wood in the middle creating a tree frame.
• Use smaller decorative .5 inch nails to hang each ornament.
• This tree was a 3, 4, 5, 6, and 7 ornament setup.
• For the odd rows, find the middle and place the first nail there and move out on each side.
• On the even rows, start on the ends, about 1.25 inches from each edge.
• Work your way in using the ornaments as a guide.
• Add a sawtooth hanger to the center of the tree trunk on the back.
• Use any kind of paint to create your ornaments. I used distress oxide spray inks.  
• Let dry.
• Paint the back with black chalkboard paint.
• Add a little bit of gold metallic paint to the top. Print out a set of basic numbers from the computer.
• Trace the numbers onto the wood ornament by covering the back of the paper with a piece of white chalk.
• Place the number onto the ornament.
• Use a pencil to trace the number onto the wood.
• Finish by filling in the number with a paint marker.
