I deviated from the Burda instructions by spacing the rows of topstitching a bit further apart and did not topstitch the center front and center back crotch seams. Also, I changed my mind about adding the zipper.
The top edges of the pockets were reinforced with twill tape. I used the Bernina satin stitch foot, #30. It put that tape right where it needed to be.
I tried them on. Yes, the waist is big, but it is waiting to be drawn in with the elastic. They fit everywhere else.
I wasn’t terribly concerned with creating perfectly aligned rows of topstitching. However, when almost finished with the topstitching, it occurred to me that I could have used the Singer to easily produce parallel rows as it can accommodate two single needles in its needle clamp.
The double stitching could have been done on the Bernina, too. Unlike the Singer, the Bernina requires a twin needle, which I don't often use. The reason? Those twin needles are pricey. Still, the Bernina would have done a fine job.
