A poor old shoemaker had just enough leather to make one more pair of shoes. He cut the leather and went to bed. When he woke up the next morning here was a beautiful pair of shoes which he was able to immediately sell. He bought more leather and the same thing happened. Eventually the shoemaker and his wife waited up and discovered it was some tiny elves who were making the shoes for them. As a thankyou, the shoemaker left a gift for the elves and when the elves discovered that they had been found out they disappeared and were never seen again.
