I am a relative newbie. I just finished a scarf using 2 different colors and so the sides are abit unfinished. I know how to crochet (sort of) but can’t figure out how to crochet the sides of the scarf for a finished edge. I hope this makes sense.
Straggling ends
You just need to pick up stitches as evenly as you can along the edge as you crochet. Probably you only need to single crochet to get them looking nice. Here’s a link I found.
