crazy birds is a tutorial from Carla Sonheim. I tried it tonight. it's a good exercise to help "free up" your drawing and lines. and can be done with kids, as well as adults (kids at heart?)
you start with two pieces of paper. draw circles on one, flower shape / petals on another. cut into quarters and arrange onto the page and draw in the bird shape. use a variety of materials
I think I could try this exercise using fabric also instead of paint
