21. Find center for long board placement

After all of the frame boards are nailed together, it is time to make the braces.  As a reminder, we will be making two mid braces and one long center brace.  However, if you have a smaller frame, you may only need one mid brace.

For this project, I will begin with the long center brace.

To do:  Measure side and mark center point (see photo).
