Here's a top view-- now the plastic table has a stone top. (2 self-adhesive flooring tiles from Lowe's, 88 cents each)
Here's a side view-- I used the middle of the second tile for a center piece on the bottom and used the rest of the second tile to fill in around the top.
The second part of this project was getting more chairs. At WalMart, I found their plastic outdoor chairs on clearance. I bought one (with the intention of going back to get a second) for only $9. We do have two chairs out there now, they just don't match. :)
The next part? To hang up outdoor blinds I bought, also at Lowe's for only $15 dollars. :)
