Becky at Nunn Design sent me some of their Open Frame Hoops to play with, and boy are these fun. They come in Silver, Copper, Gold and antiqued finishes. There are so many ways you can use these!
First, cut circles of Resin Color Film to fit behind each of the Hoops - they don't have to be perfectly cut as the hoops will hide the edges. Cut the middle out of each circle where the next smallest hoop will be, so that colors don't overlap.
I used the flat back of our Silicone Doming Tray as an easy-release surface. Arrange the colors and hoops however you'd like. As you can see, the circles don't need to be completely perfect as the metal hoops will cover the edges where they meet.
The resin shouldn't seep under the edge of this outer ring because...
1. Nunn Design rings are quite heavy and nicely shaped.
2. The silicone on the doming tray adheres nicely to the ring and the film, keeping it in place.
3. You'll be using thickened Brilliant Resin, so the chances of leak-under are slim.
I used only 3 colors and hoops for the matching earrings.
Place only the largest hoop on top of your Resin Color Film Shapes. Allow your mixed resin to set up for 30 minutes to thicken up, then slowly pour resin inside of the hoop, filling about half-way up the hoop. Allow resin to set for another 30 minutes in the rings until it's nice and thick. Then place the inner hoops, lining them up with your circles of Resin Color Film. Allow to set up for at least 24 hours (better if you have 2-3 days, so it can really harden).
The dark parts you see show where resin leaked behind the film, but it doesn't matter in this case because you'll be doming the back, just make sure the resin doesn't escape from the metal hoop.
Then flip over your pieces and dome the back side with Brilliant Resin. Allow to set up.
Place pieces on a hard wood surface and use your Spring Drill to make holes for your jewelry findings. I used 2-1/2" long sterling silver head pins in these, bent to shape.
