this is how i do it,get a jamjar,add a heaped tablespoon of shredded alkanet root ,fill the jar with boiled linseed oil.leave for 6 months agitating now and then.when the stock is prepared tip an eggcup full into another jar adding half a teaspoon full of terebine thinners.the thinners make the oil dry much faster.apply as normal.this is one of my vintage shot gun stocks i have refinished.
