What can I say, they are shelves! Each shelf does have a lip on it to stop stuff sliding out. Some shelves have old suitcases on (I like them… don’t judge me!) The last niggling thing was that I was using two cardboard boxes waiting for the perfect box, chest, suitcase to turn up that would fit in nicely.
I gave up waiting and made two crates out of my left over and scrap ply. I’m quite chuffed.
The only problem is that now my kitchen shelf with plastic stacker-boxes of food and cooking utensils looks really untidy. May have to buy more ply to make more matching crates!
