I am looking for something to put by the door to hold backpacks and coats, so they stop piling up on the kitchen table. This is what I have in mind, but the space we have to put this is only 30" wide. Can someone modify these plans for me, maybe with just two cubbies instead of three? Thanks so much. We just completed our first project (the Farmhouse Bench) and I have a list of 3-4 more I want to start.
