I really wasn't sure what I was going to build--stared at my wood pile in the garage for awhile, stared at the pallet wood in my workshop for awhile, stared at Facebook for awhile because it is an excellent distraction, and finally decided on a small bar/island/counter thingy.
I started with 4 kind of 2"x 2" (not exactly that size--just random reclaimed boards) that I cut to 35". I then added notched pallet 2"x 4" 's to the 35" boards to make two rectangles. The 35" boards were on top of the notched pallet boards at the corners. Using the nail gun, I added random salvaged wood pieces--old fence, pallet, barnwood, trim--to create the front of the bar.
