Use the settings I attached, and score & cut the design. You can make smaller or bigger version too (I tried a few sizes, before I ended up with this version).

U am using posca markers to paint this earring - this time, it is black, white and gold. You can make totally different color combinations - as you wish.

I kept the back side clear, so it can be visible that it's wood.

To make it waterproof and shiny, add a layer of glossy varnish (to front and back, and aside too.)

Wait until it's completely dried.

Add the earring settings.
