I had another skein of the hair-dyed handspun after making the mitts, and I reckoned that there was enough to weave a scarf to go with them.
It's taken a while for weaving to grab me, but it has now. I think it's the speed that your project grows. I'm also fascinated that the colours interact differently than when you knit. I'll be interested to see whether this will fluff up much more when it's washed.
