To test if my idea would work, I first cut a peice of cardboard to the proposed size and shape and tested it in the space. It's going to be perfect!
I found the perfect size tabletop for $10 at a hotel furniture liquidator. I painted the table top with some semi-gloss white paint that I had on hand.
Then, with the help of my handy-man partner Rich, we marked then cut the table top with a skill saw. I bought a single table leg from IKEA for $7.50. The table leg was attached, and then the table top was bracketed to the wall for stability. Two matching chairs were purchased on Craigslist for $10each.
