I did this with my kindergarteners once and think I will be doing it this
year with my 4th graders (we are studying Abstract Expressionism and will use it
on the tail of the canvas painting they are finishing up!)
I think the glue looks a lot like encaustic...very brittle.
I did not use a recipe...maybe half and half? I used secondary colors....I
think I got the idea from here.....on black paper...it looked pretty cool!
