Start by painting the wine glass with a coat of white paint. This will help the scallops to stand out.
Once the paint is dry, start by painting the scallops around the rim of the glass. You can use a small paintbrush or a toothpick to make small dots of paint.
If you want, you can paint the entire glass with scallops, or you can leave some of the glass showing through.
Once you're happy with the way the scallops look, let the paint dry completely.
Now it's time to add some details. Using a thin paintbrush, add some small dots of paint around the scallops. You can also add some curves or lines to the scallops.
Let the paint dry completely before using the glass.
