After a few years of thoughtful deliberation (read: procrastination, inability to get our act together to actually do it), we made a blackboard for the girls on a little wall that divides our dining room from our kitchen. A neighbor gave us the inspiration: she did this years ago for her two, now three little kids, and it's always fun to see what the kids have drawn up on the wall.
In the end, it was one of the easier household projects we've completed, and most cost effective. I think the can of paint cost only a little over 10 bucks, and two coats did the trick for making a bone fide blackboard from our formerly plain wall (covered in peanut butter finger prints!).
Of course I have dreams of using this space for writing out the week's menus, or writing a to-do list, or maybe even writing a love note to Ben.
But for now it has been very joyfully taken over by the girls, and we just as joyfully get to see their imaginings boldly on the wall.
