Here's something that I do to paint eyes, don't own a camera so will try to describe this as best as I can. Take two 1" by 2" boards 2 ft long, cut and place a thin piece of soft foam between the boards (1/8" thick will do). Then I drill three holes through the boards one on each end and one in the middle install 1/4" diameter bolts long enough to go through all the above plus 1/2" more with wing nuts. To use slide the jigs in under the foam along one board with the head exposed. I slide these in perpendicular to the to the boards and can crowd them up so use both sides, they will hangup very little. My boards will probably hold 50 to 75 jigs at a time depending on the size. Now I lay this on someting that will support it or place in a vise. Take your favorite nail, drill bit or whatever and paint all the jigs on one side, flip over and paint the other side let dry a few minutes remove and finish up however. After writing all this I may reconsider and go camera shopping!
