Step One: Very precise thread-marking of 5 parallel lines on interfaced garment section
Step Two: Baste lips in place on WS of garment, using the upper two and lower two thread-marked lines. Machine stitch in place.
Step Three: use middle horziontal line of thread marking to cut pocket opening on fashion fabric, stopping 1.5 cm from each end to create a tiny triangle. Turn lips to RS but do NOT press yet.
Step Four: Baste lips together by hand on the RS of finished lips:
Step Five: Press.
Step Six: Create pocket part. Attach pocket. Stitch down each triangle using a slightly arched stitching line.
Note that many details are omitted from this description. The purpose is to give a pretty good idea of the precision needed for this approach which, if followed, will produce absolutely beautiful welt pockets. Much practice is required. The original 5 parallel lines must be absolutely precisely sewn. I believe this to be true. Jane told me so.
