Thanks fellas. I cure them, despite the fact that they don't last long before I lose them. However, as one of you suggested, I may be brushing them too long with the HAN. As I think about it, I was originally coating the eyes and head, then moving to the threads; not much problem with bleeding then. Later, I started coating the threads first, and would also get some on the head; by the time I move to the head (maybe 30 seconds), it could be that the paint has softened near the edge of the thread and I'm brushing toward the eye, thereby getting the bleeding result into the eye. Anyway, I'll try to be quicker about it, coat the eye first, and not "overbrush".
As to the match stick, that sounds like a good idea, but I think that using various size drill bits works really well; you can adjust the size of the eye to the size of the jig, and put a pupil in the eye, just by using different sizes of bit. And Lord knows, I have enough old drill bits laying around
