One of the legends on felting origins says the new face of wool was discovered by people thanks to the Noah. You probably know the Bible story, so I focus just on his way of felting. Reportedly, he covered the bottom of his ark with sheep fleece. Under the effect of the moisture and continuous kneading with humans’ and animals’ feet, the fleece turned into pieces of felt.
Do you like the story? Of course, it did not have to be Noah, but I think it is very possible or even sure, that people discovered felt by accidental entanglement of fibers. If you are the owner of a cat or a dog with a long hair, you probably know, what I mean and what to think about the felting origins.
