Typically I machine stitch with the right sides of collar and neckline together, and then flip it but I would like to learn the method shown in the video. My patterns have 3/8" SA all around including the shoulder, neck line, and arm hole seams. I can trim 3/8" in the edges of the under collar and attach it that way but there isn't much of the neckline to sew to. Would it be correct if I extended the neckline SA of the front and back patterns another 3/8" to give the collar more body to sew on? Thanks
In the videos, the pocket jets for the cross pockets are cut perpendicular to the grain (I mean the length). Is this only to conserve fabric, and therefore only for unpatterned cloths? Would one match the grain (like for the out-breast) for the jets in the patterned case?
