Here is a movie in which I show how I release my stones:
Liquitex Varnish Gloss 118 / 237 / 946 ml
€ 10,95 – € 17,95
Liquitex Varnish Gloss – Gloss
Always apply carefully, a thin layer with a flat soft brush. Never free back and forth with your brush to prevent fineliners/marker. After applying, let it dry for at least 3 hours before applying the next layer.
