One simple shelf, five dollars, five ways . . . or more.
1 – 1×6 board, 5 feet long
2 metal angles like these – they are just used to hang the shelves on the wall – don’t need anything fancy here. Check the hardware aisle.
3/4″ screws (you will only need 4 – two for each metal brace)
2″ screws (for attaching to the wall, use a dry wall anchoring system if you can’t locate a stud or wish to place the shelf not on a stud)
1 – 1×6 @ 36″
1 – 1×6 @ 15″
1 – 1×6 @ 9″
Now use the metal angle braces to hang the shelves as you would any picture or shelf. If you cannot locate a stud in the wall, you can use a drywall anchoring system. Also, if you are planning on storing little weight (less than 16 pounds total) you can use Command strips from 3M – that’s what’s holding my shelves up!
