Willow would have never expected to be doing any cooking in charms class. She just hoped they would be baking brownies! She went to box of aprons and pulled one out that was her size. She swished her wand to the right, then swished it to the left in a circular motion while saying "Colorus Revolvo Purple." The apron turned a very nice shade of purple that was to Willow's liking. She then walked over to a station and waited for further instructions.
