So, I made a bench out of old hardwood flooring.
I laid the slats out on the ground to get the pattern right, then cut them to fit.
Then glued and screwed each slat to the next.
Since it was tongue and groove, I had to make the bottom flat with a hand planer to attach the legs that I bought.
Then I was unable to move my arms for a day.
For extra support, I put a few metal braces across the wood underneath.
Then I set up a photo shoot in my apartment to make it look all Design-Spongey.
