I've used a freebie ball of wool from a magazine. It's an acrylic yarn knitted in DK on 4mm needles.
It doesn't really matter what type of yarn you use or what gauge as the width of the head band is not particularly important.
The pattern uses a tiny amount of yarn, I think I used less than 20g so it's a fantastic stash busting stocking filler - yes Christmas is just around the corner!
