Someone told me to sew around the perimeter. I thought you were supposed to (along with stitch in the ditch top to bottom and side to side, which I did not do).
I have another one to sandwich today, so I have another chance to learn something else. The one I will sandwich today had mitered multiple borders. Now, I know why you can't just make it look right. I had to re-do 3 out of the 4 corners.
This is good however. I have the fabric for a panel that has 5 or 6 borders that are mitered, so my learning experience will stand me in good stead.
Thanks for your help.
