Our project dimensions were 7 "wide x 20" long x 3" high. This was purely based on our table size. Make sure there is plenty of room for plates and drinks, so you won't have to move your planter if you don't want to.
Hubby constructed the box for me. He took the palette and pried off the boards, which happened to be roughly 3" wide. He used nails to assemble it (to give it a more rustic look) and calked the inside seams to keep the box from leaking. Once I got my hands on it, I sealed the inside using Plasti-Dip. Hubby picked up blue, but I linked to the clear version. The Plasti-Dip is to further protect the wood. I found this as a suggestion on the internet somewhere... As you can see from the pictures, I taped off the box with painter's tape before I sprayed. This took about 4 coats. Leave plenty of time for the calk and Plasti-Dip to dry. It's also super smelly!
