Building deeps (not in depth so I posted here). Best viewed while listening to Ordinary day by Great Big Sea!

First, get some lumber, mine is 7/8" X 9 3/4"
Cut it to the lengths you want, mine is 19" for the sides and 16 3/4" for the ends.
Then I cut the rabbets for my corner joints, I leave a 1/2" behind to give me the 20" overall length I'm looking for.
Then I reset the dados and cut my frame rests in.
Easy, except the mess and clean up.





You should end up with a whack of wood that looks like this.
