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!
Staple hanger wire to the base of a wooden block. Bend wire to a unique shapes. Stretch tights over the wire and under the wooden block. Secure with more staples and coat with glue. Paint desired effect.
