Sue's hatband was a good spot for the up and down buttonhole stitch, don't you think? Since Sharon's description said that it would work well on curves, I also used it on the flowers although it's hard to tell. I alternated with a "normal" buttonhole stitch and instead of making the up and down part straight, joined the "legs" at the top. Instead of turning out like a triangle, it just looks like a bit heavier version of the regular buttonhole stitch. Oh well, I did the up/down part, honest! Don't know about you, but I hope the next stitch is different from the last two. I've run out of hat bands and sleeve edges!
