Cut the design as is - these tiny earrings can fit into any leftover small space.

I am using Posca markers for painting these; you can use any acrylic or watercolor paint. Here I used a simple red color; you can add details, like polka dots, or letters on top of it.

Once you paint is completely dried, you can add varnish to the painted side. (You'll add to the back too, but better to do it after the earrings settings.) Wait until it dries.

Use a good quality glue to add the stud earring settings to the back. 

Add varnish to the back to secure the glued earring settings, and make your earrings waterproof; and paint the sides too. 

Once it is dried, you can use your new earrings! Enjoy!
