I just discovered how easy and fun it is to paint your own eyes! I purchased several packages of 12mm clear eyes from CR's Crafts, and used acrylic paint that I had on hand.
I even painted dots in one pair of eyes :-) I'm not at all adept with a paint brush, but if you use a very small brush and a small amount of paint, it is easy to paint your own eyes.
My thanks to Michelle at Suncatcher Eyes for her tips on how to paint your own.
