Help, I think I am having a senior moment, I really cannot understand this part of the pattern
1.With RIGHT sides together, pin the center back seam of the crown, matching notches. Stitch in a 1/2" seam and press open. Machine stitch 1/2" from single-notched edge of crown. Clip to machine stitching.
I have been at it for about 2 hours and really cannot figure it out, tell me it's me being stupid!
