Now think about paper cut outs. You have to have an image in your head, you have to divide that image into shapes and colours. Those separate shapes have to be drawn on coloured paper. Neatly scissored. Then glued to paper in specific order. Child has to think what goes first, what's second and so on.
So from my perspective paper cut outs is far more challenging task for children and even teens. And it is a great exercise for their minds too.
