Story Review: The Elves and the Shoemaker

This story appeared in 1806 in Grimm's Fairy Tales.  It has been rewritten in many different versions with slight variations.  Basically this is a story of a poor shoemaker and his wife.  He only has enough money for the leather for one pair of shoes.  He cuts out the leather, then goes to bed.  During the night two elves sew the shoes for him.  He finds them completed the next morning, and says them for more than his asking prices.  He now has leather for two shoes, which he buys and cuts out and leaves again for the next day.  He again finds them done the next morning.  Needless to say the exquisite sewing he is able to make the money to pay his debts and becomes successful.  One night he and his wife wait up to see who sews the shoes.  They discover the elves, but also find that their clothing is tattered and worn and they must be cold.  The next day the wife makes them clothes.  They leave the clothes, and when the elves receive them they are delighted, and leave to never return.  However their fortunes of our shoemaker have changed forever.
