Peel and sick planks for walls. When I painted my kitchen white I left one wall unpainted, on purpose of course. I’m slowly transitioning my . Backsplash in kitchen or what do you think for the other bathroom babe?
I like the idea of the wood like fence. You could have one pannel for every child in your classroom and then use it as a growth chart for toddlers. When the child moves up or leaves the centre you can give it to the parents. Use Pallet wood.
