Flow tank top from Norah Gaughan Design Collection, vol. 2.
On my third start, I have about eight inches done. While I love this yarn, I don't know if I would recommend it. It is fairly treacherous to work with. I've spoken to several people on Ravelry who are also knitting Flow and they're all having problems with the yarn.
New yarn alert:
This is Birch from Teva Durham, Loop d Loop/Tahki yarns. 90% cotton, 10% silk. There's a nice little booklet cleverly named Loop-d-Loop by Teva Durham volume 2. Here's a link to the Birch page at Tahki's site color card.
