There is a simple answer: “Ask the jar.” It is an old used-up candle jar filled with tons of things he can draw. Sometimes he chooses one word or two, sometimes he gets five and tries to combine them together into a one picture. In some cases, it proved to be quite a challenge.
Well, you can fill the jar with whatever you want. There can be just words or pictures of specific projects you find online. You can have two jars – one with stuff you want to draw (whale, superhero, lost underwater city) and one with how you want to draw them (watercolors, crayons, ink). You can have your kids write them themselves and add to them every time they have an idea but not enough time to execute it. Possibilities are endless. Have fun.
