Cooking is chemistry with this DIY spice rack! Spice-filled test tubes hang suspended from a gorgeous walnut frame. Make your own with this easy tutorial!
Despite a cabinet full of spices, we only use a handful of them in our everyday cooking. I wanted to make it easier to see when we’re running low on these essentials, and clear out the cluttered cabinet. This DIY spice rack displays our favorites in test tubes suspended in a beautiful walnut frame that sits proudly on our countertop!

One of my goals for this year is to start using woods other than pine and plywood in my projects. Other than the cutting board I made for my mom for Christmas, I’ve stuck with cheaper boards for fear of messing up more expensive types. But it’s time to throw caution to the wind and upgrade to walnut and maple!
Of course, you could easily use pine for this project and stain it any color you want! You can find my samples of the most popular grey wood stain colors here.
- One 1×4 board
- Hardwood like walnut is priced per board foot, so you only need to buy a 2 foot long piece if you want to save money.
- 20mm test tubes with cork stoppers
- 21mm diameter Forstner bit
- 18mm inner diameter rubber O-rings
- It took some trial and error to find the right diameter O-rings to fit into the test tubes snugly. These are a perfect fit, and stay in place without slipping!
- Table saw
- Drill or drill press
- Sander and sandpaper
- Wood glue
- 12″ clamps
- Paint, stain or cutting board oil (for hardwoods only)
- Mineral oil (for hardwoods only)
DIY Spice Rack Instructions
Create a Test Piece
Before I started drilling holes in my beautiful walnut board, I created a test piece in a scrap piece of 1×4 to determine the spacing. First, I arranged the O-rings so they were evenly spaced 1/2″ apart. The O-rings are 1 1/8″ in diameter, and I left an extra 3/8″ on the ends to fit into the side pieces later on.
Then I marked the center of the O-rings for the point of the bit. Here’s what the final marked-up test piece looked like. Add up all those measurements, and you’ll get the length of the top piece (mine was 9 3/8″).
I drilled holes with the 21mm Forstner bit along one side of the test piece to make sure I had the spacing the way I wanted it, and to make sure the O-rings held the test tubes correctly. Looking good!
Clear as mud, right? 😉 If you want a better idea of the spacing and the rest of the details of this project, click below to download the free woodworking plans!
Cut the Rack Pieces and mark placement
With the final spacing decided, it was time to start cutting the good stuff! I cut one 9 3/8″ long piece and two 7″ pieces out of a walnut 1×4 board. Then I transferred all the markings from the test board onto the 9 3/8″ piece.
Drill Holes for Test Tubes
I had debated getting a drill press for a long time, but I’ve used it in my last two projects, so it’s earned its keep. 🙂 I first used it to make circles for my IKEA Lego table, and now it will make perfectly sized holes for this DIY spice rack!
If you don’t have a drill press, you can use a regular drill with the same 21mm Forstner bit. Just make sure that the bit is straight as you drill, or the hole will be crooked!
Place a sacrificial scrap board under the walnut board so you don’t bore into your table! Line up the point of the bit with the X mark, then clamp the board into place.
Then drill the hole all the way through the board. You’ll know when you’re through when the light wood colored shavings come out. I love how the walnut shavings look like chocolate!
Continue drilling holes until you have all ten completed. Then sand all three pieces with progressively finer grits (I used 120, 220 and 320 grits). I got to test out my fancy new Festool sander that my husband gave me for Christmas. I wish you could feel how smooth these boards are now! It’s amazing!
Cut Dadoes in Side Pieces
You can attach the sides to the top several different ways. I thought about using pocket holes, but I didn’t want to mar the beautiful walnut with wood filler or plugs. You could also nail it together with small finish nails.
I’ve included directions for both of these versions in the free woodworking plans you can download below!
But I decided to go with a hardware-free design with dadoes cut into the side pieces to hold the top in place. This isn’t as difficult as you think, and you don’t even need a dado blade on your table saw to do it!
Mark a line 1 1/2″ down from the top of each side. Then measure the width of your top piece (usually 3/4″, but it isn’t always exact) and mark a second line for the bottom.
Set the height of your table saw to 3/8″ (this tool makes it super easy!) Then make two cuts just inside the lines you drew on the face of the board.
Then make additional cuts in between to clear out the excess wood.
Test the fit to see if it fits snugly. If it needs a little more room, cut the tiniest bit off with the blade and test again. It’s better to be too tight and sand it down than too loose!
You might have a series of ridges on the inside of the dado from multiple passes of the blade. I used a scrap piece of 1/2″ plywood wrapped in sandpaper to even out the bumps and create a clean groove. Be careful not to round over the edges!
Glue up the Rack
Before permanently gluing the spice rack together, I tested the fit one last time and checked to make sure the test tubes hung the way I planned. Perfect!
Apply wood glue to the inside of the dadoes on all three sides.
Fit the top inside the sides, and clamp it into place. Clean up any glue that has squeezed out from the joints. I used scrap wood on the outside to prevent the clamps from indenting the surface of the walnut wood. Leave it clamped for at least a few hours to ensure the glue has dried.
Stain, paint or oil Your Finished Spice Rack
Now you can paint or stain your finished spice rack. If you used a beautiful hardwood like this walnut, all you need is a bit of mineral oil to really bring it to life! The walnut turns from light brown to a deep, rich color that will stay that way even after the mineral oil has dried.
Use a clean cloth to get the oil into all the holes. Allow it to soak into the grain for 5-10 minutes, then wipe off the excess. To protect the wood from the inevitable spice spills, I also gave it a coat of cutting board wax.
Label The Test Tubes
It’s hard to tell the difference between coriander and cumin by looking at them in the spice rack. You could always remove the cork and give it a sniff, but I didn’t want to risk using the wrong ingredient!
Instead, I used my Silhouette machine to create labels for each test tube. The font I used is Bebas Neue, and I arranged the letters vertically so you can read the entire label at a glance.
After applying the labels, slip the O rings over the top and push them down to the same point on all the test tubes. This will let them hang evenly in your DIY spice rack.
Fill Test Tubes with Spices
Now it’s time to clear out some of that cabinet clutter! I had quite a few duplicates of these spices, and some of them expired years ago! I tossed the oldest ones and filled the test tubes with the rest. A small funnel makes this process much easier!
Each test tube uses about half of a small spice jar, but I plan to buy better quality spices in the exact amount I need in the future. Spices can last up to two years in an airtight container, so keep that cork in the top!
Let’s Start Cooking!
This DIY spice rack doesn’t take up a lot of space on the countertop, but holds all our favorite spices within arm’s reach!
It’s easy to pour out an exact measurement into a teaspoon or tablespoon, unlike those plastic jars with the sprinkle lid. I also keep these tiny spoons on hand to scoop out smaller quantities.
Our new spice rack almost makes me want to cook more (almost!)
This DIY spice rack is part of a new monthly challenge I’ll be participating in this year. This group of talented DIY bloggers will create a new project based on the theme for that month.
This month’s challenge was organization, and these bloggers knocked it out of the park! Check them out!
