Use my settings, or adjust them to your machine or materials (e.g. it would look great with white acrylic as well). Cut the design.

I am using fine-tip white acrylic markers to paint these little stud earrings. If your engraving is deep enough, you'll find it pretty easy to add the colors to the right spot.

You need to wait until it's dried completely.

Use a strong and clear glue to add the earring settings to the back. I am using super glue, a small dot of glue is enough.

Wait a bit, until it's dried, then you can add a coat.

You can use spray, or a bottle of liquid varnish for the top coat. You need to add to both back side, and the front, as well as the sides to make sure, that it's covered completely. It will last longer, securing the earring settings, and making it waterproof.

Once it's dried, you are ready to use. :)
