Tune children in early to textures. Go on a texture hunt around the house. Make the exploration into a blindfold game where children use their fingertips and tactile sensations to identify where they are. Stuff it with pantyhose. Artists love a challenge, so they try to solve visual problems.
Artists plan ahead, so what they think becomes reality.
Ask questions and plan explorations to ensure that your children observe, try out new ideas, and end up with creative results.
