Flour is a hard one for many people, and I understand it. It gets everywhere, it makes hard wood floors slippery and it can be breathed in inadvertently. However, it makes the best snow scene; the best race track for matchbox cars, the best dinosaur stomping ground, the best beach; the best cafe; the best hills for little figurines to smash down. Plus, it's oh so soft and lovely to run through your fingers.
