Now look up inside the cuff, there is a crease previously ironed into the under cuff. Mark the crease with pins all the way around the outside.
CAREFULLY, turn the sleeve and cuff right side out. Pins mark exactly where the finished cuff folds back over the sleeve. Fold, pull the pins out, and iron with lots of steam. One down, one to go.The reduced seam bulk makes a huge difference. Time to add button holes, tape, and buttons.
