A similar story was written by the authoress Beatrix Potter (1866-1923) called The Tailor of Gloucester first printed in 1902. In this, the tailor came downstairs one morning to find a waistcoat (=vest in American usage) which he had left uncompleted mysteriously finished. The implication was that elves had been at work.
Miss Potter wrote that the story was absolutely true. Was this an incident of elves or fairies intervening?
The tailor whose shop it was bore the name of John Samuel Pritchard and he was only too pleased to use the publicity he had accrued from the story. Some years later, the explanation came out.
Pritchard had two assistants. One night they were somewhat inebriated and decided that the walk home would be too arduous for them. They therefore entered the tailor's shop (one of them had a key) and slept there all night.
Next morning they completed the waistcoat before leaving. Not an elf, as far as we know, had set foot in the shop.
