If the idea of a three day weekend with nothing to do seems like torture via boredom then take a gander at these neat DIY projects and get to building!
You might not be able to build an entire TARDIS from scratch in three days, unless you have some serious carpentry skills, but a Star Trek apron is doable, and so are many of the other fun projects on this list.
This Labor Day weekend you can build something to be proud of, or head in to work on Tuesday complaining about being hung over... I choose you DIY project!
