I recommend this kind of art endeavour. Can’t really make a mess, and by the end it has a substantial feeling that’s close to wood carving. Lots of paper on the roll acquired in a lumber yard (Arctic Paper), and a white glue and water, and you are off. Build up in whichever way you want and then use a utility knife to carve away what’s not needed. Paint to taste, fit in a frame and there you are. It’s an easy way to lose yourself for a few hours, when the rest of the uproar of the day is over.
