Petrichment's Kitty Self Scratcher Tutorial:
Step 4: Drill the base holes. Hold the brushes in an arch on top of the base, and mark where you want the insertion holes to be. Using a sharp blade, cut away a small hole in the fabric and padding (if you skip this step, the drill bit will get caught on the padding). Drill the two holes into the wood, but not all the way through. Fill the holes with hot glue. Shove the ends of your brush arch into the holes.
