Day 3 of our Baby Advent Calendar was to finish the dioramas that I started in January (check out the Instragram I posted from step 1)! I used old wooden wine & whiskey boxes, painted them grey, added fabric*, and screwed them into the wall. Toss in some animals and trees and we're good to go! I'm sure there will be add-ons as time goes... I'd love to make little ladders & hooks from the bottom, but this is a good start and our son loves them!
*I glued fabric to cardboard (Elmer's) and then screwed the boxes to the wall. When I placed the fabric in the boxes you couldn't see the screws :)
