I used Knit Picks Swish Worsted, and the pattern for the hat is Bright Beret by Amanda Keeys, and for the mittens, Bold Banded Mittens by Zöe Mellor. I did make minor changes to each; in the case of the hat, I knit it at a gauge I liked better (much tighter), so I just made the larger size so that it would come out newborn-sized (or slightly larger) in the end. For the mittens, instead of a seam across the top, I just used the ever-handy Kitchener stitch, and am well-pleased. I am also forced to admit by the very wee size of these mittens that my youngest is not so wee anymore (nearly two, in fact. Time does fly).
I might just get back to the cardigan later, but in the meantime, there are cupcakes to be eaten.
