Step 3: Measure + Mark for Holes

Place one dowel piece flush to the edge of the wood. Make a small mark and measure on your drill bit from there, or measure the dowel piece up against your bit directly.

Dowel Measure

Place tape along the drill at the length of the dowel piece. This is a simple DIY guide to let you know where to stop when drilling the holes where the dowels will be inserted.

Step 4: Drill Holes + Insert Dowels

Step 6: Sand Smooth

You can do this by hand but an orbital sander will make your life a bit easier and your arm not so sore in the morning. Starting with an 80 grit and sand down every part of the shelf.


Repeat that same sanding process with a 120 grit until silky smooth.


Step 7: Stain or Paint

Depending on paint or stain, be sure to follow the instructions on the label to ensure you are applying properly. Mixing it up is fun! Try adding one color to the outside and another color to the inside.

Step 8: Add Hanging Brackets

Install the hanging brackets of your choice. Adding a hole into the wood where the nail will go is always helpful to keep the shelf as flush to the wall as possible.
