... away playing in China, but I thought you may have missed this tutorial on playing with alcohol. Done in 2014, it's a favourite on my YouTube channel. You could always subscribe while you're over there too.
You can find a written tutorial on the technique here as well if you prefer to read instead of view.
I love the way that the dropped alcohol (use a mask please!) looks over the spray-misted alcohol.
These backgrounds lend themselves easily to journal pages or paintings, as you can see in this progress photo.
It's a fun technique and I encourage you to give it a go! Just remember to use full-strength (non-drinkable) alcohol, and keep it away from your mouth!
