I'm traveling a lot and would like to offer Touch Drawing in places where it might be hard to get the paints and rollers- I'll be in Kenya in a few weeks. I'm bringing tissue paper and oaktag quality paper but wonder about paint as Im flying. I also want to make sure participants can do this after I leave. The Duo inks which I use here cannot fly and is very expensive and hard to get. I've been testing acrylics and woodblock inks using a slow drying medium- its ok, but a bit tacky and the tissue pulls hard. What has your experience been? Thank you and Happy New Year.
