Relief liners are used in glass painting to avoid colors spills and to create a good looking relief effect.
These liners are supplied in handy 20 ml tube with a plastic nozzle.
The more you slice the nozzle further from its tip the thicker the outline will be.
Once the outline is prepared with these liners, fill the inner areas with WamiQ transparent or crystalline colors.
Use on the clean and dry surface of glass or mirror for relief lining.
