I managed, somehow, to track down the info sheet from the yarns I purchased at the show in San Francisco earlier this year, and lo and behold, the place where I bought the yarn (but not enough of it!) has a website! While perusing through their color selection (and drooling over more than a few of them) I think I’ve identified one of the yarns as Seabreeze. The other is going to take a little more work, but I emailed them and did a desperate plea for help. So all may not be lost. Keep your fingers crossed!
In the meantime I’ve been industriously working on the front of the blue-green sweater, and am in the process of shaping the first side, since it’s a keyhole neck. It’s actually knitting up surprisingly quickly, and I really like how the colors have come out.
