Thanks to mama kate getting me searching some blogs for references to using Flora Trendsetter. Both were using it for scarves though. I'm really not a scarf person. So I did a little digging on my own, found another similar yarn called Cancun, and then found these:
Two tank top patterns using that type of yarn, I'm very excited! They seem to use one strand along with something else, in one pattern it is cotton, not sure for the other. I could probably make a pretty cool looking top if I used a black or light blue cotton with this bright cobolt-y blue novelty yarn.
