Because I am a new sewer I am very law abiding and follow instructions to the letter even if they seem a bit odd - but after topstitching the entire length of the jacket's hem with all of the jacket fabric under the arm of the sewing machine (kind of rolled up as tight as I could) I realised that maybe I should have started on the opposite side from the one shown in the picture in the pattern. As I have 2 more of these to make soon - is there any reason you would start on the side indicated in the pattern rather than the opposite one?
