The challenge: to join the ends of my mohair tube scarf to form a continuous loop. I don't think I can make the join truly inconspicuous. The alternative is to make it obvious.
At the same time, the principle of letting the yarn do the talking is appealing. So, I'm going to try embellishing the join with a crochet ruffle. It's the same yarn, but a deliberate variation in texture and bulk. I'll see how it looks when I'm done.
