Would anyone out there have the pattern Vogue 7958. I've been working on sewing this dress for my granddaughter. Anyway there just doesn't seem to be proper instructions for pattern piece #10 & 11 (back) where it states Pin back interfacing (10) to wrong side of bodice back (11), as shown. Baste. Sew invisibly along foldline. I've done this part and now I'm lost. Do you cut this back section down the center line as it does need to be open for button holes and buttons? The next part directly following talks about gathering the skirt.
I hope someone out there has sewn this pattern and can give me the instructions for this part.
Thank-you so much in advance.
