Poor Davis. He's a 4th child, AND a baby, which means his socks are frequently lost. Plus, he is not a walker yet, and those flimsy baby socks, even with baby shoes on top, just don't seem warm enough. and, as much as I love knitting baby booties, I need stuff that is faster than even the simplest bootie pattern.
So, I came up with something even simpler, believe it or not.
Knit-to-fit baby slippers
Cast on 28 stitches over size 6 needles. Knit roughly 20 rows for a one-year-old, or knit to the thickness of the baby's upper ankle. (optional: add 3 sets of short rows at either end of the slipper by knitting 8, wrapping the next stitch, and turning.) (also optional: cast on more for a cuff.)
Knit 2 together at the beginning of the next 4 rows. (for smaller babies, I suggest casting off 6 at the beginning of the next 2 rows)
Knit until the slipper is as long as the baby's foot, plus a row or two to grow on.
Knit 2 together all the way across the row.
Break yarn, thread a large tapestry needle, and instead of casting off the stitches, thread them onto the needle and gather. Stitch up the front. Stitch the back seam. Crochet a chain, thread it through the top of the slipper.
Stick them on your baby as fast as you can!
