Why does the back trouser panel get seam allowance for the fly?
Just to preface, I asked this question on the video comments at Vimeo. I have since re-watched the videos and gotten my answer. In the spirit of documentation for anyone else that gets this question, I am deciding to post both. My original question: I've got a question to the drafting of the backside waist. You say the finished line is made up of 1/4 waist + (3*3/8"+ 3/8" + 2*3/4") (i.e. seams, ease, darts). I'm scratching my head about the 3*3/8" bit. Two of those are the side seam allowance of the backside piece + seam offset into the front for easier pocket handling as mentioned in one of the videos. In the drafting video you say the final 3/8" is to account for the fly. I'm confused as to why we would need to account for the fly on the backside. Could you please clarify what you meant with that? Thanks!
All seam allowance is added to the undersides. Doing so displaces the side seam, moving it forward. Makes it easier to find the hip pockets with your hand. Otherwise you’d be reaching back
