Finally sewed up the equilateral triangle hat:
And made a new hat. I brought a few new stitches to try out, and ended up with this twist stitch diamond pattern. It seems like a big pain at first because it's all togs and knitting through the back loop, but once you get the hand of the left and right twist stitches they get easier and faster. I'm finishing it off with a little tail; not sure how long it'll go. I thought it would be too big for an infant but it's quite dense and not eager to stretch
