So this week I've been doing mono-printing with my first graders. I decided to use watercolor pencils. It has worked ok, but will probably go a different direction next time around! I've done oil pastels in the past ...both water soluble and regular. I think the regular oil pastels...and then using a spoon to rub it worked the best. Live & learn!!!!
I have a bunch of small water bottles always at the ready!!!
