My new place had a large empty space on the bathroom wall, but there were 2 large stainless Q hangers still on the wall waiting to be used. The only thing I bought were things to put on the shelf itself. All of the materials were items I already had around.

Tools Needed:

Scissors
Screw Gun
A Chip Bag Clip

Step 1: Materials

Materials include:

(2) Wooden Crates (I believe I got at Wal-Mart, maybe $5 - $10 each)
(1) Roll of Twine (Previously purchased from the Dollar General)
(4) Wood Screws
(4) Rubber stoppers (The little rubber feet things with sticky on them to secure stuff
(2) Small Hook Screws
(2) "S" hooks
Wood Glue
Masking Tape

Step 2: Braiding

Although the twine says it is strong, I decided to braid it in order to make my shelf a bit more secure.

I just eyeballed the distance between the wall hangers and the spot where I wanted the shelf to hang on the wall, then pulled 3 times that length from the roll and cut. Then I used that long piece of twine to measure and pull the same amount from the roll and cut. This will give you the 2 "arms" that the shelf will hang from.

Then I took one of the lengths and divided it into 3 equal pieces. I used the Chip Bag clip to hold them by one end, and braided. Next, I repeated this and braided the second length of twine.

If your two braided pieces are not even, just trim them with scissors. Then tie the ends so that your braid does not unravel.

Step 3: Measuring & Hanging Options

At first, I was just going to hang the braided twine pieced from the Q hangers, but it is much easier to attach the twine to the shelf first, and then hang it. So I found 2 small S hooks.

Step 4: Crates & Shelf Hanging

I had 2 wooden crates that I was using just to hold supplies in. So I lined them up to where the edges were even to decide how to attach them. Then I applied a thin layer of wood glue and screwed them together. Be sure to wipe and smooth out any excess wood glue that may ooze out from between the seam.

I let my shelf dry overnight before hanging it to allow the glue to set.

The screws I had on hand that would secure the crates without going through to the other side had rounded heads instead of flat ones. So I used 4 rubber stoppers to cover them in order to prevent anything you put on the shelf from getting scratched.

Next, I drilled a small hole close to the back, top corner of the crate, and screwed in a small hook. Then, on the opposite corner repeated this step.

As seen in the fourth picture here, I looped one end of the twine from the inside of the shelf, through the crate handle, and through a small hook screw. This allows the shelf to hang level. Once I had the twine looped correctly, I tied the ends together. To make sure my knot didn't come undone, I also wrapped masking tape around the knot. If you put the masking taped part of the twine in the hook screw, this also helps keep the shelf from slipping around.

Once the shelf was hung, I didn't want the wall to get scratched so I attached 4 small round foam stoppers to the back of the shelf.
