I'm currently working on a way to tighten the stretch in the button holes so the buttons don't end up being stretched right out of the hole. I think if I add a narrow crochet trim to the outside, I'll be good to go (I could do a buttonhole stitch around the outside of the buttonholes, but I want to keep it with yarn!).
Overall, even if I think doing buttons is a pain, it is very nice to have the finishing touches on. Overall, they all stay in place and look very nice! I still have one more to finish up, but I should have that done in the next few days. It's one of my favorite invented patterns!
