Here are some little shelves we made for the kitchen. So simple.
Curved piece of plywood with a little strip of Corex on the edge to hold stuff in, carved into the hard foam, and attached at one point to the window frame. That’s all.
After it was all dry fit, I shot a squirt of expanding foam in the cut in the foam, then put the wood in to stay. I figure since that stuff’s basically glue, it’s there to stay when it dries, and it oozes out around the edges and fills all the voids.
We made bigger ones on the other side anchored to the fridge side cabinet, and H.W. made a couple for his little zone.
The rest of the camper project
