I know this comment is a couple years old, but yes you can work it flat. Start with Judy’s magic cast on, and distribute over two needles (search for “agnete cardigan start” on YouTube to see petite knit demonstrate the technique). You can then knit one, slip one purlwise w yarn in front, which will create the tube without working in the round. First stitch of the row is slipped, last stitch is knitted.

This will also give you a provisional cast on edge which makes it easy to close the tubes with a kitchener stitch (look up YouTube for how to Kitchener in the round.)

I just finished mine today using the methods described above and am really happy with the results!

Thank you for the lovely pattern!

Todella kiva ohje ja kaunis pääpanta. Kiitos!

Thank you so much! You can work with double-pointed needles instead – just divide the stitches evenly between the four (or three) needles and work the stockinette stitch. You will have the same tube with no seam. Or you can work flat, but you’ll need to seam the sides together if you want the headband to be double-layered.
