I didn't know how to post a photograph in a comment, so instead of commenting on cathyc's post I'm writing this. I'm in the middle of sewing in the yoke on my Silver Belle. So far, I don't think it's going to pull up in the middle but I could be surprised when I finish putting in the left side. Here is how it looks with just one side sewn in.
I should have the other side finished after I drink my coffee!
