I combined last week's and this week's TAST. As I mentioned last week, I'm not crazy about the Bonnet stitch and I didn't find it in any book either. But, I managed to make something simple of it along with this week's Up and Down Buttonhole stitch.
I did find a nice video tutorial at Mary Corbet's Needle n' Thread for this week's, the Up and Down Buttonhole. All of Mary's photo and video tutorials are very good!
