Kitchen Sink Batt (she's currently out of everything in the store, but it looks like she'll be back next week) and those usually have a tiny bit of Angelina in them. Angelina is a very fine metallic fiber you can add in when you card fibers. There is just the perfect amount of sparkle in the finished yarn and in the knitted fabric, you see the sparkle just as it disappears. It almost makes you wonder if you imagined the sparkle, but then you see it somewhere else. It's kind of sneaky that way. Hmmm, sneaky sparkles - sounds fun!
