We made this last year, but for some reason, I didn't get around to painting it until a couple weeks ago. I found this tutorial for making the board - with fold in legs so that it stores nice and compact in the garage. Technically, all I did was find the tutorial and paint it. My husband did all the cutting, sanding and assembling; but that's not important :)
With the nice weather we've been having, we just keep this on the back patio and the kids are having a great time playing with this.
One thing different we did - I felt like the board was too big for just one hole, so we cut 3 different sized holes. And then I painted it blue with orange stripes for some fun detail.
