I couldn't get a good photo of the edging but the yarn overs can be seen if you look hard.
The worst part is weaving in the edges, especially because there's no good method to follow. I can't weave in the ends like I would for garter stitch because of the loose weave of the shawl and because of the yarn overs. I ended up weaving through the beefy parts of the stitches a few times, just to make sure the yarn stayed. It's not noticeable since Homespun yarn is very forgiving.
Next time I'll try a different method of binding off than the basic bind off. It doesn't stretch enough for my liking.
