I regularly purge unnecessary items from my house but I have a really, really hard time throwing anything away that could conceivably be used in a future project. But that's not what I'm talking about today. Today is for making something out of stuff that seemingly doesn't have much of a use.

But you can totally take it a step further and add flickering, electric tealights, or even hang them from the ceiling with fishing line to make them look like they're floating above the great hall at Hogwarts.
