Back from DeKalb. Success! I got yarn for three projects, plus the ribbon I needed to fringe that other scarf. My Trellis yarn came in today too, I've started the shawl with it. The first two rows were the hardest, after that it's just three double crochet, two chain, three double crochet,
ad infinitum, decreasing on both ends til you get a point. Basically a granny square except it's a triangle. Then I'll fringe it - though I haven't decided whether to use the black ribbon I got or the yarn I'm making it with. I'm thinking the ribbon, because this yarn, though beautiful, unravels REALLY easily. I see why they call it Trellis yarn - it's two black threads with satin insets of three shades of blue. Interesting to work with, for sure.
