What's the best way to sew a seam? Not sure, get out a book. It's good to have encyclopedia type reference around on lots of topics. This one is on needlework. I use the internet too, but what if the internet is down???
I was attempting to attach the arm to the body of the sweater. They suggested the ladder stitch, though they called it something else. Invisible!
A few more seams and some tidying up and I'll be finished. I'll show it to you when I'm done.
