I've been working away on the TTJ and I'm almost done. I have to say, the knit of the sweater is so thick that for me, a single thickness buttonband would just not do. Especially since I knit the sweater a little more form-fitting than the pattern called for and if I want to be able to button the thing, I'm gonna need a bit of reinforcement.
I like crochet bind-off instead of whip stitch.
There you have it. Oh and a note, there's no way that a single YO would accommodate a 3/4" button with my tension so I went back and did two YOs instead. Now to move on to the sleeve buttonbands...wheeeee.
