Molly, one of the artists I worked with last week, did a classic activity but gave it a new name!! Noodle Doodles. The children loved the name as much as the activity.
Step One: With a crayon draw a large doodle with swirling moves.
Step Two: Paint in the doodles with noodles of color!
I love this, so creative, and I think I did this as a kid too! Good to be reminded, we lose so much when we grow up, forget some of our childish inventiveness. I have to try this out with my kids, my nine year old will like it.
