Same method I use. I can't focus close enough with my current contacts, so I went to Hobby Lobby and got a magnifying visor and the max magnification lens. I think ideally, it would be best to use one of those work lamps with the circular florescent bulb and the highest power magnifying lens in the middle as possible.Originally Posted by Lee Shively
Additionally, I've had best luck with a 10/0 brush. I've got a saucer into which I've dropped three or four drops of spotone #3 and let it dry. I've been using that saucer for about a month and I'm not out of spotone yet. To apply the dye to the print, I lightly drag the very end of the very tip bristles of the brush (at the point where I can barely see it with a magnifier) across the spot and slowly build up to just under the density I want.
