Dollyce, they were fun to do and pretty quick. As fast you knit you'll have them done in couple days.
I will say that the yarn I used felted great, but it's not particularly soft. Also the double sole feels cushy at first, but gets crushed pretty quickly. This of course doesn't make them less beautiful or less useful, but thought I'd give my thoughts. Does anyone know if some wools are softer when felted than others?
ETA: I should also add that I have sensitive skin plus some nerve damage in my feet that causes problems. The yarn used for mine should be perfectly fine for normal skin.
