Make a reusable dry erase calendar from a simple poster frame and paint chips, because sometimes it's useful to realize you have a big paper due Monday when you're making your weekend plans.
From Silver Lining. You know where to get paint chips, and you could even hit up the local thrift store to find a frame. But you can also get one on Amazon for $21.99 (18"x24") or Target for $9.99 (24"x36").
