You make SOO many of these, I really hope you will eventually make it a regular store piece that anyone can buy. Ebay ones rise sooo fast in price its almost impossible cause the tiger pieces are so well done! LOVE these, my favorite idea you have come up with for Windstones.
We get them in bulk from the supplier, but you can purchase eyes just like these from Van Dykes taxidermy. They call them "wood carver eyes" [link] There are also other great eyes available (these are cast acrylic) [link]
