Ok, you've ripped your boards, now it is time to cut them to size. To start, make an 45 degree cut on an end of a 1" x 2" - with the WIDE side of the wood facing out. Remember, we want our frame to be 2" thick (NOT 1" thick.)
Note the knot at the end of this board. Since we have some extra length, we will make our first cut past the knot.
