These came out light years more cute than I expected them to.
I forgot to take a picture of just the base color. This was two coats of KleanColor Sweet Orange, which is just adorable. I started off with drawing a small line of black about halfway up the nail I wanted the art on.
Then, I drew two convex (or concave depending on the angle you're looking, I suppose) arcs from that line to the tip of my nail.
Then color in between those lines, and there's your cauldron!
Next, I added the moon and stars with a stamp plate. Do try not to get part of the moon on your cuticle, but really that's up to you.
Then I added some wisps of steam rising out of the cauldron with some silver.
There we go!
