Hi! I just got my first set of circular needles and wanted to make a scarf with vertical stripes with them. Well I've made about 5 rows so far, but I'm realizing that I'm just making a huge tube - I'm not really making a scarf. I followed the video directions on this site, but it never really says how to make a flat scarf - or if that's even possible. I've seen a lot of patterns for scarves with horizontal stripes that definitely have ends! I really want to know how to do that before I take apart what I've done so far. Any help would be great! Thank you so much!
