A friend of mine in the USA told me about American whiskey painters few years ago. Here more details.
The idea to try alcohol for painting was stuck firmly in my head (I am sure there is more correct idiom in English, but I am sure you recognize the feeling). And yesterday I tried brandy. It works perfect, mix with ink and does not run around as water when added to my inks, as there is only 60% of water is in this wonderful thinner.
I highly recommend (at least if any brandy left after you used it usual and more practical way))) to try.
We were sitting in the kitchen, friends drank brandy, I was driving that day. So they generously granted me the painting material for this aloe flower..
