Is anyone bored? Does anyone need a craft book? No. Because here are 100 ideas, 100 impulses, 100 possibilities right in front of you. Or better: very close by. For example, leaves. Leaves are an excellent learning material: natural phenomena, botany, mathematics, color theory, material experience, sensory training, movement – all of this is contained within them. Leaves can fly, swim, dance, leave traces, stimulate the imagination, make the cycle of life tangible, and teach wonder.
