(Note: Model (my son) had just woken up in the morning, but always ready for a photo opportunity, was happy to don the headband.)
I really wanted a headband for myself, but decided to knit a child-sized one, to see if I'd even like it. I also decided on a ribbed pattern to give it a litte more stretch.
Yarn: Worsted Weight (In photo above, I used Red Heart yarn (inexpensive), color 2940 Beach)
Needle size: #9
Cast on 74 sts (Depending on head size. My next attempt will be for an adult-sized head and I will use 84sts)
Knit one row
K2,P2 for about 2 inches, or desired width
Then, Knit one row (loosely) and bind off on the next row (loosely). Sew up the ends and you have a headband. It's a simple as that.
*You could have all kinds of fun making these. I'd like to try it in some fuzzy yarn. I'll be sure to share some pictures of my different projects.
