Testing out the sanding bits with Rotary tool
Getting clean, smooth leather edges is a common challenge for many leathercrafters. Without the right tools and techniques, edges can end up rough and uneven, ruining the entire project. Sanding, burnishing, and applying edge paint require patience and practice, along with the proper tools, to achieve great results.
This is how I prepare the leather edge before applying edge paint.
Step 1: Sand the Leather Edge
I used to use sandpaper, but recently a friend gave me a set of sanding bits that attach to an electric spinner and I'm going to try it out today.
Check out this video below—it's my first try! I got this result in less than 1 minute of sanding.
Sanding is an important step because, it helps prepare a flat and smooth edge before we apply the edge paint.
Step 2: Apply the First Layer of Paint
Next, apply a thin layer of edge paint. You can use either acrylic dye or edge paint, depending on your preference.
Some people use an awl or similar tool to apply a thin layer of paint because it picks up only a small amount of paint.
Step 3: Dry Burnish with a Canvas Cloth
Use a clean canvas cloth to burnish the edge. This creates heat through friction, which helps the paint bond better to the leather and prevents peeling later on.
Step 4: Burnish with a Wooden bit
Now, use a wooden bit burnisher to further smooth the edge. This step creates a smooth base for applying more layers of paint. The small wooden burnisher also helps round off the edge, making it look nicer.
Tip: A wooden slicker can also work well for this step.
Step 5: Sand Again for Smoothness
After that, I use a wooden burnisher to smooth and round off the edge. This prepares the surface for additional layers of paint. Don’t worry if some of the paint comes off during this step.
Tip: A smoother edge will make the next layers of paint adhere better and give a more professional finish.

Step 6: Apply the Second Layer of Paint
it’s time for the second layer of paint. I like to use an edge paint pen with a rotating head. This tool holds a good amount of paint and applies it evenly along the edge.
Step 7: Wait for the Second Layer to Dry
Allow the second layer of paint to dry completely before moving on to the next layer. This ensures each layer adheres properly and helps avoid smudging.
I will apply the third layer once the paint is dry, followed by forth. Some people sand the edge with higher grit sandpaper, like 800 or 1000 grit, before applying the next layer. They repeat this process—sanding and applying edge paint—until they get the perfect result.
Tip: The higher the grit number, the finer the abrasive particles and the smoother the finish that can be achieved.
Here’s my third layer of edge paint… I’m actually pretty satisfied with it already! :)
Step 8: Apply Additional Layers (based on your expectation and preference)
Apply more layers of paint based on your desired result and preference. Keep adding layers until you're happy with the finish!
I repeat the process for fourth layer, building up a smooth and durable finish.
Here's my forth layer of edge paint!
If you have a lot of leathercraft orders to fill, the sanding bits are a game-changer for reducing production time. They're affordable, so even hobbyists can give them a try. Not only do they speed up the process, but they also improve the overall finish of your leather projects, giving them a more professional look.
