The workshop was inspired by the gorgeous snails and butterflies by Woodlark®: Ashley was so kind as to let us use her idea (you can find templates at the link provided), so please visit her blog to find more beautiful activities that combine sensory experience with eco-friendly art. Also, I highly reccomend you follow her on instagram.
Instead of butterflies and snails, we drew and cut out of thick cardboard a hedgehog and a squirrel, and decorated them by glueing different types of beans and seeds on them — any animal that has a good surface to cover (like a squirrel's tail or the hedgehog's squills) works fine.
