These tiny earrings are easy to make, just a bit of color, and ready :)
Use my settings to cut with 10W laser these tiny designs. (Great for using scraps). I used 3mm pine plywood. I like to make deep engraving, so the paint won't get out from the lines.
Use water-based acrylic markers to paint them. Wait until dries.
Use clear coating to seal the design. Do not add it to back, only the sides and the top. Wait until it's completely dries.
With strong glue, add the earrings settings to the back.
Wait again, until it's dried perfectly. Then, you can add the varnish to the back side too. Wait again for drying, then you are ready to wear/sell these tiny earrings.
