I'm posting this because I learned how to do a blind hem today. See?
This will come in handy if I ever have to make another party dress for Rachel. I looked at this tutorial for folding the fabric, but what made the difference between getting it right and giving up (a la party dress) was reading the instructions for doing this on my sewing machine. I don't have a manual and couldn't get the download to work when making Rachel's dress, hence the giving up.
I now know how to use four of the 21 feet Mom had for this sewing machine.
