A while back someone posted some suggestions on making washes with rubbing alcohol and India Ink. I searched and can't find it so hopefully you all will have some good suggestions. What I remember was something like this. Light - 1 teaspoon per bottle of 70% or 91% alcohol Medium - 2 teaspoon per bottle of 70% or 91% alcohol Heavy - 3 teaspoon per bottle of 70% or 91% alcohol Am I on the mark or way off?
Clarification: On the 90% alcohol, I only used it one time because I had a bottle and was "desperate". Try to use 70%. The 90% (although strong) is okay on wood, etc. But it can wreak havoc on plastics.
