Here’s a quick video to make this easy little flower.  Should be able to rustle up enough for a pretty headband in no time.

But if you don’t want to bother with a video it’s basically:

10sc in adjustable loop and slip stitch to close

(1sc, 1hdc, ch1, 1hdc, 1sc) in next sc

slip stitch into next.

repeat the above two lines to the end and finish off.
