I am making a series of models that have sharp edges, and I want to create a thin line of glitter along them so that the edge will sparkle a specific color when turned under a light.
I have tried most of the obvious options, including painting pre-mixed modge podge with glitter on to them with a brush, but I am not happy with how any of them came out as it was difficult to control the concentration\density of the glitter, or to maintain a thin enough line due to the thickness of the glue.
I have also considered using glitter pens, but I am unable to find any that have a transparent medium carrying the glitter. They all create colored lines.
I have a series of refillable artist's pens designed to use with acrylic paint that have an aperture that's wide enough to carry the glitter that I would like to try to use, but I am uncertain about what medium to use to carry it. Neat PVA is too thick, a mix of PVA and water is too thin and won't give me the control that I need, and most of the thinner glues that I'm aware of dry too quickly and would probably destroy the pens.
Does anybody have any suggestions on what I should use.
It needs to dry transparent, to adhere to a surface painted with acrylic paint, and be thin enough to apply as if you were drawing a line with a biro while carrying the glitter with it. And it needs to dry slowly enough that it won't just clog the pen aperture.
Is there a specific product, or a way of modifying a specific product that might achieve this?
For example, is there an artists' product that could be used to thin PVA, other than water?
