There are actually 2 ways you can make these earrings, whichever works best for you is the right way to go!  These could be made into buttons using our Clear Button Backs instead of earring backs, or magnets, or whatever you want:

Option 1:  

1. Cast a thin layer of black resin (Brilliant Resin + Black Resin Colorant), allow to set up for at least 12 hours.
2. Demold, make sure top edges are even, put your sticker on the top and rub down, then place on Doming Tray.
3. Dome up the top of your castings with clear resin and allow to set for at least 12 hours before handling to prevent fingerprinting.
4. Glue earring posts on backs, the strongest hold will be a few drops of thickened resin, but if you don't have any mixed up you can also use ZapAGap Superglue.

Option 2:

1. Cast a thin layer of clear resin, let set up for 2-3 hours.
2. Apply stickers face-down onto surface while resin is thickened but still sticky, rub down with mixing wand in case any air gets trapped.  Allow to set up for full 12 hours.
3. Demold, place on Doming Tray, and dome up with Black Resin.  Allow to thicken for 1-1/2-2 hours, then insert earring posts into resin for strong hold.
