A great project to use wooden offcuts, old hooks and some shelf brackets. I'd make the shelf with a surround so I could store more things in it and not worry about it rolling or falling off plus it hides some of the contents for a cleaner, more organised look
Like that there is no bottom shelf - easier to clean floor, and larger middle shelf too. Want to use nice wood to stain. No wood against back wall want wall paint to show through. Put Formica on top counter - flat against wall- not "rolled" back splash that wastes space..
