These fold-over baby booties are especially warm because the leg is knit in Two-Color Mosaic Rib Motif. To make a cozy slipper in a child or adult size, you can easily adapt the pattern.

Each sock pattern in Knit 2 Socks in 1 uses The Everyday Sock pattern for all of the measurements and stitch counts in a choose-your-own-adventure-style pattern.
