Knitting a bow is super easy! And makes everything super CUTE!
Adjusting size for bows is really easy, just cast on more stitches to make wider and knit more rows to make longer.
For the newborn hats, I typically cast on 10-15 stitches and work in all knit for four inches. Take a long piece of thread and a darning needle and wrap around the center until secure. Add a quick seam at the corners to secure to the piece.
