After this picture was taken I finished the Xs at the top and knitted the garter stitch border. But then I had to decide what to do about the edging.
Apparently Estonian practice means knitting the edging separately and then stitching it on. I do really hate sewing things on. I mean, sometimes you have to, for example in order to stabilize the shoulders and neck of a sweater. But for me, it's usually a procrastination trap.
Another reason a person might need to sew on an edging is if it has to be knitted from the outside edge in. Some lace patterns only work in one direction. I thought I had better swatch the edging from the straight side out, and make sure it would make points.
