I've been going through a scarf making phase, and a few weeks ago you saw me knitting scarves and sewing scarves. Well, they're baaAAaack!
For this scarf, I trimmed the edges with a silky ribbon.
Just simply sew the ribbon onto the edge of the scarf.
As you can see, I didn't sew on the absolute edge. I sewed in a bit and then later trimmed the edge of the scarf to meet the edge of the ribbon.
And there you have it!
