My advice if you try the blackboard pumpkin idea, which I still maintain as awesome, would be to buy a craft pumpkin. I think I’ll pick up a few of them if Michael’s has post-halloween sales. I feel like a pumpkin made for crafting would be better for a project like this…and it would be cool to be able to reuse my beloved seasonal countdown.
Still: Awesome.
