These directions are for making the scarf for toddlers
Pattern for scarf: 13 stitches and about 25 inches long; GARTER STITCH only. Start doing the button hole at about 21.5 inches in length and about 4.5 inches from the end. Cast off at the 6th garter stitch and only casting off 3 stitches. I used this very helpful video to cast off the button hole.
Pattern for bow: 10 1/2 straight needles and normal/med size yarn. Pattern: 16 stitches and about 6 1/2 inches long. Once done knitting, simply grab some yarn and wrap around the middle to form the bow. I secured the bow to the scarf with needle and thread. Then I simply used the bow as the “button” to hold the scarf. You simply grab the bow from the button hole and that’s it.
