It's Berroco Quest in color 9860 (which I don't see on the site, so possibly they don't make it anymore?).
I bought this way back when, when I first started knitting and and didn't really know anything about what yarn was appropriate for what projects and what would be nice to knit with, etc. I purchased this to make a novelty scarf for my cousin. The idea was that I was going to knit this together with a strand of an eyelash yarn, so that the effect would be similar to the Fireworks scarf pattern in Stitch 'n Bitch. Well, the resulting knitting looked nice but was a real pain in the a** to knit - I discovered that I really dislike eyelash yarn. so I never finished it. And thus I still have this yarn. It is 100% nylon, and I don't really know what to do with it. I really like the color, and it does have a lovely shine to it. I don't know, maybe a purse? Anyone have any ideas.
