These are called 1-hour baby booties. The pattern can be found in Stitch and Bitch Nation. They really only take about an hour. But the straps take about another hour each. Maybe I labored too long attaching them. Tonight I hosted my own Stitch & Bitch, which was responsible for my finally finishing the straps and buttons.
I'm pretty sure there's a reason babies don't wear booties. I'm pretty sure the booties will fall off as soon as the baby moves its legs. My stitch & bitch comrades assured me that it's enough for the booties to look nice in the gift box and displayed in the baby's room.
