Maybe for Charlote's Web (?) Water color crayon resist artwork, an Original watercolour painting by Kirsten Bailey, but could be adapted for a children's art activity. Great for a fall wall hanging or spider picture for the fridge!
Any skill level can do this class and along the way Increase your watercolor skills. Learn new techniques. Learn how to only use one brush and no pencil! Practice painting loosely and intuitively. Have fun!
