I first saw this pattern in the Mason Dixon Knitting Book, and wanted to make it then. But I've really been wanting to make it lately. It's the Curve of Pursuit blanket. I am in awe of people who can design stuff like this. My math skills are certainly not up to this sort of thing.
I've been working on FH's hat, still not sure that it's actually gonna work, but we'll see. I've knitted about 1 inch of the visor portion, need to knit about 4 more inches, then move onto the actual hat part.
