I hosted several Kids' Art Camps this summer and compiled a bunch of photos! We made some great art! The monoprints below were so simple to make and came out beautiful. I still have some hanging in my house. The kids loved making these. Instant gratification! I posted the instructions below.
Paint your image very thickly on a cookie sheet. Then mark lines through it using the end of the paintbrush -see the lines in the tree trunk?
Press paper on the baking sheet, rub firmly and peel off. Voila!
