Thank you, Ladies!
I made some bias tape from the dress fabric. I was too afraid to use my machine to sew it around the armscye--wasn't sure I could keep along the original stitch line. So, I used a running stitch (I haven't totally forgotten how to hand sew ), then trimmed the seam, folded the binding over and stitched it by hand. It certainly won't win any beauty contests, but I think it turned out well enough to do the job.
The dress is in a pillow protector in the dryer right now (yes, another late night and I have to hit the road in the morning ). If the dress stays together, I will get some pictures, after ironing, of course, and share.
