I'm also trying to do the seed-stitch version of the ear flap and figuring out the increases is taking a while. I've got it, but I keep forgetting to do in the increase row. And I think I need to make a smaller size than the pattern calls for since I'm using heavier yarn (it calls for DK and I'm using Cottontots).
So, things are brewing but nothing really got done today. Oh, I did cast on a simple hat for DD in that self-patterning yarn, but I knit 1.5 rows and got tired of it.
