After all the comments about definitions of gnarled I feel much better. I've been trying to redo the wool thing, but really, those loose things you buy in the shop are sooo not photogenic. I put a pic behind it, so it would be more cheerful but not much I could do with those things. Look here:

I tried all sorts of things and in the end totally lost it. That's when I came up with a pic of a little village rising up from behind gnarly grey mountains... Oh and look (no not you, OhLook) there's also a gnarly tree in the village!

I'm having so much fun with this.
By the way: I don't knit. This wool was my mother's who did knit. She knitted socks, dozens of pairs of socks. Great socks. I still wear them. And she gave me these bundles of wool so I could repair the socks in case I got holes in them. Yeah, right...
