I use my general purpose scissors to cut brown card into small shards. They have hard-wearing carbon blades and slice precisely to make the bark of an elm tree. They are supplied in a smart PVC wallet which I cut to create a stream. I tear some ivory tissue paper to form cirrus clouds. I crumple more to add stratocumulus. I stick this to versatile paper that's perfect for drawing and sketching using traditional Japanese glue. I give it to Dad, who puts it in a 120 gauge thick black sack and tells me to do something useful for once.
