Lady bettles made from fimo. little messyfish loooves them. I steered him away from a pack of 100 erasers in the shape of lady bugs, by promising to make him some. Still "plastic", but at least they are homemade. He helped me make them too!
Painting gesso on scrap wooden boards... (garden art with mushrooms gnomes and flowers in the pipeline)
Mixing sand into the wet paint and experiencing the sensation.
"Plaster of Paris" moulded volcano. When set mix washingup liquid, bicarbonate of soda and some food colour. When ready pour over some vinegar for a messy vocanic oozing lava experience. (I happened to have black and red food colour on hand, which I would never use in actual food!)
We also put together two big bags of toys for the "poor children". Which implies we are rich.... We are not! but little messyfish can't get his head around the concept of floods yet. We are donating toys to the flood affected queenslanders.
