A scarf patern on circular needles?

How do i knit the scarf so that its not connected

Cast on on one end of the circ, knit across, and then switch the needles just like you would your straights. You can knit back and forth on circulars just as easy as on straights. Good luck, I bet you’ll love knitting “flat” (back and forth instead of around and around) on circulars!
