I made these.... now what?!

There's a ton of moss around outside since the snow, our lawn will need completely reseeding! I decided to make the best of the situation by making these cabochons, though I'm still trying to think of ways of using them!A few people have inspired me to try some felty stuff as I'm not sure how they will work being completely see-through, as if I attach a ring finding for example you will be able to see it. I'm going to see if I can drill close to the edge without breaking them tonight.
