Another Tale of Felt

Another story is about a pilgrim, traipsing along a hard, dusty road on his pilgrimage. His feet are sore and tired. He sees bits of wool from the sheep being shepherded near the road. "Cool," says he, and picks some up to put in his sandals. His feet instantly feel better (of course), and when he arrives at his destination, he has felt.
I tried this, I put bits of wool in the bottom of my kids shoes before they went to school. They weren't hugely impressed. But when they came home they had small, foot shaped pieces of flat felt. It was a bit smelly. But I put it in the washing machine, and now I have a couple of labour free, prefelts.
