To get the effect, start with an opaque blank insert (I find black works best). Have at hand a disposable spoon and a smal, sealable container with some dish soap and water you can agitate to make tons of bubbles.
Using an aplicator (I use a flat silicone brush), apply a very thin layer of UV resin. Use the spoon to scoop the soap bubbles onto the resin-coated surface. Quickly put it under a UV light to cure the resin. I clean any overspill with a craft blade to keep it neat.
Once all facets are done, brush the mica powder of your choice onto all the surfaces and cast in clear resin.
I appreciate that. So many times someone will roll and we all have squit and imagine in the number in our heads because you can't see the damn number it rolled on.
Those blue ones you made are really nice too! I like how you made the yellow numbers the highest and all the rest white.
