We wanted to see what kind of salt and paper worked best for our 2nd grade watercolor resists Kimono paintings.
I made a joke about Salt n Pepa but of course my 2nd graders did not get it.
So here is our experiment.
Pre-test..we used Mediterranean sea, Kosher Salt, San Francisco and table salt.
First we tried it on 90# white Pacon paper
Then we tried it on Watercolor paper
The San Francisco Sea Salt seem to work best.
