I can not find the post about painting jig heads but in my opinion this is the best way to paint eyes. I use a regular panel nail for the back ground use the head end dip in paint hang on rack to dry I use a toaster oven on 150degrees for 8 to 10 min depending on how many jigs are in oven. cut the sharp point off of the nail and use it for the center of eye, then back to the oven. I use an alcohol lamp ( for rod building ) to heat the jig for powder paint, does not leave residue on jig so the paint will stick better. lighter colors use white for back ground and black for center. black heads I use yellow back ground and flo. orange for center of eyes. Your miliage may vary.

good luck.
