Sometimes the simplest ideas are the best, like this one:
For your artistic child or children, or the kids you want to encourage to explore their artistic abilities, set up an ‘invitation to draw’ with inviting materials, a nice work space, and an interesting subject to study and turn into art. It can be pencils, colored or not, paints, markers, and whatever subject captures your fancy and that you think will draw them in. Flowers are a natural, but so is anything with interesting structure, texture, color, curves, you name it. It can an object, a photograph, even other ‘art’. Let them explore their abilities as well as their creativity in an ‘inviting’ environment.
