Actually AJ did. After much pestering from me (sorry!) he bought 2 boxes (4 chalks all) for us to try out.
I’ve drawn lines already in all our kitchen cabinets. Tomorrow I will continue with the cupboards. I think it’s better to do that in the morning so I could draw the lines better.
So there. I hope I won’t see creepy insects crawling in there anymore.
No more shrieking episodes for me, please.
