The zipper is already in and I am sewing the side seams and sewing over the zipper.
Maybe my manual will tell me. When in doubt......LOL
I read through most of the manual and it did not mention whether I could or could not backstitch with the dual feed foot attached. I even tried calling the 800 # which said to call anytime but they are closed until tuesday morning for the holiday weekend. Oh, well. Thanks for your help!
