This is my third decorated egg, and I'm really happy with how this one turned out. The egg was cleaned out and died a light blue. I then dipped it in water with nail polish on top (it floats on the top like oil - if you do this, use a plastic cup you don't want and be aware that the polish will eventually eat away at the plastic, creating leaks).
For the inside I cut a small styrofoam ball in half, spread white glue over one of the halves, and liberally sprinkled pink craft sand on top. I should have waited for it to dry but I was impatient and kept working on the project. I mixed some glue and nail art fluff (similar to flower soft), to make the little bushes. I added more glue to a small twig and added more fluff to make flowers/leaves on it.
I used hot glue to attach the foam ball to the egg, and the same glue on the unicorn's feet (I had to do this twice as it glued to the sand, which pulled off as the white glue wasn't dry yet).
I used three strands of 'friendship thread', a glittery metallic thread, braided to make the loop, also glued on with hot glue.
