Need Extra Fine tip for painting with Pebeo 160
I have been painting glass objects with Pebeo Vitrea 160 paints, curing them in the oven. Even though I have purchased several 0.5mm tips and bottles to try to get very fine detailed lines, they are always too thick.
Is there any way I could possibly locate an extra fine paint pen for this? What about using a Sharpie pen and the coating it with Pebeo before curing to preserve it?
