I grew up surrounded by LEGOs. With two older brothers, it was pretty much a given that there was always a spaceship or a race track under construction. But once all the children left the house, my parents were left with so many LEGOs, they didn’t know what to do with them!

Instead of simply throwing them out or giving them away, consider these projects. Not only are they grown-up-appropriate, they’re fun to make and might even bring you back to your own childhood days!
