I think these are absolutely Amazing!!!
I'd love to see the completed set when your done.
As for the Air/Wind debate, I was thinking it was Wind....then I'm like hmmm movie classics hello..."The Fifth Element" so I used this as a good excuse to watch it again, not like we should need one...lol, and it's...surprise, surprise,
Air, which they were only able to replicate by blowing on the stones, representing wind of sorts, but the element title was Air.
Good luck, and have fun crafting...in this case quilling!!
