This is a Knick Knack shelf that you can put almost anything that you want on it. Its original purpose is to hang on the wall and put video game cases, and accessories on.

Materials needed:

2, 6" x 36" x 3/4" pieces of poplar (a type of wood)
1, 2" x 36" x 3/4" piece of poplar
Carpenters glue (wood glue)
Clamps (C-clamps, or Bar clamps)
Optional:
- A nail gun w/ nails (powered w/ air compressor)
- A pint of paint (any color)

Time to Build: 1-2 hours + 24 hours for glue to set

Expenses:

2, 6" x 36" x 3/4" pieces of poplar = $10.78
1, 2" x 36" x 3/4" piece of poplar = $2.37
Wood glue (owned) = $3.47
Clamps (owned)
Paint (leftovers from previous project/owned)
Nail gun (owned)

Step 1: Gather Materials Listed, Layout the Shelf to Visualize the Idea

Having the materials gathered, and visually planning out how this is going to be built, will be key in the construction of this.

Step 2: Cut the Two 6" X 36" in Half, and One 2" X 36" in Half

This will be an extremely simple design, I was able to get the wood at Home Depot, and have the employee cut the wood in half for me.

Step 3: Glue the 2" X 18" to a 6" X 18", As Show in Picture

Doing this will allow you to hang this shelf on the wall.

Use the wood glue to attach the wood, and use a clamp (optional) to have the glue set. Use a nail gun to firmly attach the wood.

Step 4: Use More Glue to Attach the Pieces of Wood

Use glue to attach the rest of the wood, use the nail gun to make a sturdy construction.

Step 5: Optional: Paint, and Hang on Wall

After the glue sets, you can customize this shelf however you want! I am choosing to paint it a gloss white, and hanging it in my dorm room in college, to hold my video games, and books.
