I just finished these - a VERY quick knit (and I am not a quick knitter) They are comfy and warm! I think I would prefer them to be slightly more felted. Will toss them in the washer again and see. I used Lion Brand Alpine Wool - they came out very fuzzy after felting, so I used my hubbys hair clippers to "shave" them. I love the embroidery embellishments that many on Rav have given them. If I get up enough guts, I may give it a try. I ordered some WOTA from KP on Friday so I can make more of these, they were so much fun to knit....and such instant gratification - my favorite kind of knit item

I have large feet, so I increased the cast on to 68 sts and they came out just right. Link to the pattern:

Pre-felting:
FO, post felting and shaving. Well, camera angles mean alot...my ankle looks abnormally wide in the second picture here!
