I built a picnic table from plans on line, only I beefed it up using 2x6's instead of 2x4's. it just needed to be heavy duty as I'm not a small person. Plus I wanted it to sit a little bit higher then the ones at the store. All in all I think it turned out ok. since I made it I've had people offer to buy it, so I sell it and build a new one. makes for a nice weekend project.
