Step 1: == Prep the Ring
As you can't see in the photos, the process actually started melting the ring, so this step isn't necessary. Not to mention the ring just looked dirty when I was done. :((
Step 2: == Cut Away the Bow
Step 3: == Get Rid of That Bow
Then I take the buffer and run it over the ring in an attempt to smooth it out and am only half-successful. The thing likes to really eat away at the plastic. Eventually I get to a point where it's good enough. The paint I'm using should fill in anything I missed.
Step 4: == Paint on First Layer
Using the picture of the character as a reference and a messy doodle for a concept sketch, I start with the skin and the first two colors of the horns You need at least two layers for most colors, because the light shines through one measly layer of paint and it looks shoddy.
The kind of paint I used would be reactivated by the glaze, so I'd have to paint a layer of glaze over every color to keep them from accidentally mixing. To remedy this, try painting a layer of modge podge or white glue over each color instead, and then going over the whole thing with glaze. It's important to find glue that dies clear, purr-fur-edly with the same finish as your glaze.
Once the paint is completely dry, I paint on at least two layers of glaze. The first layer should be thick and deliberate, the next one can be more brushed on. The reason I do this is because goache is water-based, and has a tendency to smear and smudge when glaze is first painted directly on it. So I but glaze over each individual color to prevent that once I'm finished and want to glaze the whole thing. You can also use the glue technique mentioned above if you think it will be easier. If you do this be sure to wait for each layer to completely dry before you continue painting!
Step 5: == Rinse and Repeat
Step 6: == Amaze Others With Your Awesome Ring!
The ring was a cheap plastic thing, so it didn't really sur-purr-rise me when the actual ring bit broke off. To remedy this, I used the dremel tool to grind away the ring bit and hot-glued a loop of elastic in its place and now it works purr-fectly. You can also attach a blank ring with a pad or tray on it made specifically for making custom rings. These are sold in craft stores, look for jewelry findings.
