Knitting pattern, headband, quick and easy knit (3 Sizes), Coeur Headband

This time it should be a headband for children and adults. A headband that is easy to knit
with no seams.
Every year I always have the same problem: It's cold in spring and fall, but not cold enough for a hat.
There had to be a solution. And what could fit better than a headband?
And what I think is particularly great: It is suitable for Mommy and Me outfits.
And you get all that with these detailed step-by-step instructions.
