When my children were toddlers they used to bring home all sorts of interesting bits and pieces of nature. Pebbles, stones, seeds, sticks, leaves and everything in between. In every visit to the park or after school they will be safely kept inside their lunch boxes or pants pockets
At first they were just stuff, that sometimes annoyed me, but one day they showed me a "sad man's face" inside a nut seed and then I began to see.
These are the characters I created with some of these treasures.
