I don’t use the method shown in the pattern, Amanda. Start and stop basting the piping or flat piping about two inches from the place where you want to join the ends. Take the left part of the unbasted piping and lay it down along the bodice seam to the join (underarm seam in this case). With a fabric marking pen make a vertical mark on the piping at the join. Do the same with the free piping on the right. If you have piping, trim the cording at the join on each side. Cut each piece of piping about a half inch after the vertical mark. Open each piece and align the right sides together and sew a half-inch seam. Trim the seam to a quarter inch, and finger press the seam open. If you have cording, replace it so the two pieces butt together at the join. Refold the piping over the cording, lay it down on the bodice seam, and finish basting the final four inches. I’m sure the way shown in the pattern is correct, but this works for me. I’m sorry I don’t have any pictures.
