Dazzle aire or sparkle yarn has solid fibers of Creslon or nylon. If you look closely the yarn has clear fibers running through that are clear antron. And yes I have skeins of many colors purchased from Ben Franklins, most of my yarn is Sparkle Aire or something like that. I happen to be 150 miles from home right now and sorry I can't check. I know some people have expressed disappointment in his sparkle caddis patterns. Not me they are still the first caddis pattern I go for. All I can say the solid colors of antron do not have the same effect as the "sparkle yarn". If you have the book Challenge of the Trout, read the chapter on caddis if memory serves me I think Gary explains the bubble attraction to clear antron.
