The swatch I made for my Habu's Kusha Kusha Scarf is a tiny knitted sculpture.
I am 2/3 done on the scarf and predict hours of happy play when wearing it.
I bought the kit directly at Habu textiles.
I love the other versions I see here and there on the net.
Purl Bee offers the pattern for free on their website, but really it makes no sense to knit it without the steel.
There a still more photos of this swatch in my flickr account. Try a search with "kusha".
