This has been a good little thing for us - I simply call it "the black board"
It is a simple wood board, painted black, with colored clothes pins on it. This is where we put invites or important papers that we need to act on. I've had this up for a few years, but it was held up by Command strips, and they keep coming loose because the board is slightly warped, so if we push on the top clothes pins, it pulls the board off of the wall at the bottom. So it's been falling off the wall for the past few months and the clothes pins have broken apart or gotten lost as it falls. Tonight, I decided to be productive and finish this as I waited for people to go to bed. So now it's up and should stay - I painted new clothes pins yesterday and drilled holes in the board and repainted it. Now it's nailed to the wall and ready to go. Yay
