Worked great! I didnt have masking tape so I used duck tape. I used Lisa Palvekas UV resin, alcohol ink for color, & a UV light. When I peeled off the tape the bottom resin was a little wet so I put in back under the light with that side up. When that was cured I applied clear resin to the entire back to make sure the resin wouldnt fall out since the cells arent very deep. I know have a beautiful pair of pique-a-dour stained glass earrings. Thanks for your help!!
