DIY Faux Stone Cabinet Knobs: A Budget-Friendly Upgrade

Refacing your kitchen or bathroom cabinets can dramatically change the look of your space. However, the cost of new hardware can quickly add up. Have you ever been shocked at the price of cabinet knobs? A single stone cabinet knob can easily cost $14 or more! When you consider outfitting an entire kitchen, like mine with its 30 knobs, that quickly escalates to over $400. That’s a significant expense just for the finishing touches.
Determined to find a more affordable solution, I embarked on a DIY project to create the sophisticated stone look for less. This guide will show you how to transform ordinary knobs into stunning faux stone accents without breaking the bank. Get ready to give your cabinets a high-end makeover with a budget-friendly twist!
Unleash Your Creativity with Polymer Clay
The key to this cost-effective transformation is Sculpey, a versatile polymer clay that hardens when baked in the oven. Polymer clay is an ideal medium for crafting faux stone textures due to its malleability and ability to hold intricate details. I’ve seen other crafters use it to create realistic-looking faux rocks, which inspired me to apply the same technique to cabinet knobs.
Initially, I was unsure of the final outcome, but I was pleasantly surprised by the results. The finished knobs genuinely resemble real stone, adding a touch of elegance to my cabinets. This DIY project is not only budget-friendly but also allows for endless customization and creative expression.
Choosing the Right Knobs
Before diving into the how-to guide, it’s crucial to select the right type of knobs. I used ceramic knobs because I already had them on hand, but metal knobs also work perfectly well. However, wood knobs are not suitable for this project, as the polymer clay may not adhere properly to the surface.
Keep this in mind as you gather your supplies. The choice between ceramic and metal is largely aesthetic; consider which material best complements your existing cabinet style and the overall design you envision.
Materials You’ll Need
Here’s a comprehensive list of the materials you’ll need to create your own faux stone cabinet knobs:
- Sculpey (or your preferred brand of polymer baking clay): For this project, I used translucent and black Sculpey to create a variety of stone effects. While Sculpey offers a pre-mixed Gray Granite color and Granitex collections, using translucent and black allows for greater versatility and customization. One 2-ounce package of Sculpey can cover approximately eight 1-inch knobs, making the cost per knob incredibly low – around 25 cents each!
- Ceramic or metal knobs
- Baking sheet and aluminum foil
- Oven
- Optional texture enhancers: Kosher salt, Martha Stewart Crystal Fine Glitter, nutmeg, and a wood rasp. Note that not all of these are necessary for each faux stone look; the specific materials depend on the desired effect.
Step-by-Step Guide to Creating Faux Stone Knobs
Follow these detailed instructions to transform your ordinary knobs into beautiful faux stone accents:
Step One: Prepare the Clay
Begin by pulling out half of one section (there are typically four sections in a standard package) of the Sculpey clay. Knead the clay until it becomes soft and pliable. This process warms the clay and makes it easier to work with, ensuring a smooth and even application.
Next, form the clay into a pancake shape, approximately 1/8 to 1/4 inch thick. The diameter of the pancake should be slightly larger than the front of your knob. This ensures complete coverage and allows for some overlap that can be neatly trimmed later.

Step Two: Apply the Clay to the Knob
Carefully form the clay disc around the front of the knob, pressing it gently to adhere to the surface. Ensure that the clay covers the entire front of the knob and extends slightly over the edges. This will create a seamless and professional-looking finish.

Use the back of a table knife or a similar flat tool to smooth the clay and conform it to the back of the knob. This ensures a secure attachment and a clean, even surface. Remove any excess clay and smooth out any imperfections.

Step Three: Baking the Knobs
Follow the baking instructions provided on the Sculpey package. Typically, this involves preheating your oven to a specific temperature and baking the clay for a set amount of time. Place the knobs on a baking sheet lined with aluminum foil to prevent sticking and ensure even baking.

Step Four: Cooling and Installation
Once the baking time is complete, carefully remove the baking sheet from the oven and allow the knobs to cool completely. This is crucial to prevent cracking or damage to the clay. Once cooled, your faux stone knobs are ready to be installed on your cabinets.
And that’s it for the basic forming and baking process! Now, let’s explore how to achieve different faux stone looks.
Creating Different Faux Stone Effects
The beauty of this DIY project lies in its versatility. By using different techniques and materials, you can create a variety of stunning faux stone effects. Here are some of my favorite methods:
Travertine
For the travertine look, use translucent Sculpey. After forming the clay into a pancake, press one side of the disc into kosher salt that has been scattered on a flat surface. Follow the baking instructions. After baking, soak the knob in a glass of water to dissolve some of the salt, creating the characteristic porous texture of travertine.

Black Granite
For the black granite effect, use black Sculpey. After forming the clay into a pancake, press one side of the disc into very fine glitter. The glitter will add a subtle sparkle that mimics the shimmering crystals found in natural granite.
Marble
To create a marble look, use 1/8 of a section of black clay and two 1/8 sections of white clay. Form each color into oblong pancakes. Stack the pancakes with the black layer in the center. Twist the stack once or twice, then form it into a ball. Finally, form the ball into a pancake as described in Step 1. The twisting and layering will create the beautiful veining characteristic of marble.
Gray Granite
For the gray granite effect, bake a small amount of black Sculpey. Once cooled, use a wood rasp to grate about 1 teaspoonful of the baked clay. Form a translucent pancake and press one side of it into the rasped material. The rasped black clay will create the speckled appearance of granite.

After pressing into the rasped material:

Natural “Corian”
For a natural “Corian” look, form a pancake of translucent Sculpey and press it into nutmeg. The nutmeg will add a subtle texture and warm color that resembles the subtle variations found in Corian countertops.


Experiment and Customize
These are just a few examples to inspire your creativity. Don’t be afraid to experiment with different colors, textures, and materials to create your own unique faux stone looks. Try blending different colors of clay, using various spices, or incorporating other crafting materials to achieve the desired effect. The possibilities are endless!
If you’re not happy with the final result, you can easily pry the clay off the knob and start over. Use a side cutter to carefully cut the clay and then pry it off with a screwdriver. This allows you to refine your technique and achieve the perfect look.
If you’re planning to make a large number of knobs, consider purchasing Sculpey in larger bricks. This will save you even more money and ensure that you have enough clay to complete your project.
