knitted headband

[Northknitter]

Hi,
I have a ball of yarn left over from a scarf.
Now, I would like to knit a headband to give with the scarf.
Anyone have a pattern for a headband? I found one on line but it tied up at the back. The type I would like is all in one that just pops over your head. Thank you in advance.
ps...it is so cold here that I could wear it today.
it is barely over freezing and this is the first day of summer weekend. Brrrrrrr....
