The woman who had to bake for the fairies.
A woman was out tending the cows. She went through a door and found herself in a fairy hill. She was made to bake for the fairies and could not get out until she used all the flour. The flour level didn't change, no matter how much she baked. One fairy told her how to get the flour used up. She was not to eat any of their bread, but make a bannock for herself with the leftover meal. This worked and the flour came to an end. The fairies blessed her, but cursed her teacher. She was granted any gift she wanted. She asked to be able to use a sickle faster than anyone.
The contributor did not know if the gift passed on to her descendants.
