During the great garage reorg, we un-earthed a candle making kit I received as a gift a million years ago. (I seldom exaggerate!) The kit contained sheets of bees wax and a bundle of cotton string for the wick.
My son asked if he could make one. Why not? I showed him how, and then he made several. So did my youngest and her sleepover guest. The kids created a candle scape on the hearth, and then lit every single one. The sweet scent of honey permeated the living room.
Such a simple craft, and yet we all enjoyed ourselves immensely.
