To make a simple cape like the one I wore yesterday, you need a nice fabric, not too thin, a lining that goes with it and two closures (Chinese Frog, buckles or other).
Stitch at 1 mm from the edge along the basting stitch and fasten the closures.
Now you’re pretty with your cape. You can throw it over your shoulders and play the star. Well worth the two hours you just spent, right?
