A couple of weeks ago, I picked up two more of these garden stools at Big Lots, who had them on clearance for $14 each! (Very few were left, but maybe you can still snag a couple.) Don't worry about the color; they're super easy to spray paint.
And, I had been on the hunt for some bistro chairs all summer when I spotted these at Garden Ridge. They're light weight but actually comfortable to sit in, and they come in a variety of colors (red, green, yellow & black) for $20 each. I was just about to buy some cheapies at IKEA when I found these, which I think are alot cuter. (I bought the table at Sam's earlier this summer.)
At this rate, my patio will be looking fantastic by Christmas!
