Hi Angela, Secrist Real Eyes Brand doll eyes are heat safe up to 270 degrees Fahrenheit. There are some lovely colors. They range in size from 26mm to 12mm. Hope this is helpful. Leah
Ya, those would be good but I think the 6" minis need like a 6mm eye. So glass would be the next best thing as you can get them small. Maybe Mr Secrist will have some smaller ones made now that they offer the sculpting dvd.
