Here is the hat I knit to match the Kissy-Fish longies. It's Small Mama, Sweet Sugar's pattern, found here. The first time I knit it, it was the wrong size. Luckily, it's a quick knit so it wasn't hard to redo it. I always run into size issues with patterns as I tend to be a loose knitter. Generally, dropping needle sizes 1-2 steps corrects this, but not this time! I think I'll miss this hat when I ship it to its owner.
