I'm mingling a couple of my crafty obsessions. I fell in love with the moebius scarf the first time I saw one, and similarly after a friend told me about felting. What fun. I have one of Cat Bordhi's books where she talks about making felted boots. I decided not to make real boots, so at MuseCon I started making a tiny boot -- it is now finished (

You can google "felt" and "boots" or "shoes" and find a bunch of patterns and ideas online. I've made several pairs, with mixed success -- the bottoms tend to wear out, and they can be slick -- I finally decided I was doing it wrong. The soles should be made of a very durable, coarse wool (such as Dorset or Shetland), not fine wool (like Merino Ramboullet) -- or, better yet, made from leather or rawhide. OTOH, slippers like these can be pleasantly warm when the temperature hovers near zero.
Also, I'd worry a bit about the wood meeting up with the pebbles.
I wonder if the thing to do for boots to be worn might not be to make the whole boot out of something nice and comfy, but to put a sole on -- either something woven for purity, or plastic -- for height & waterproofness and traction.
