Cut Cape Opening
Again, you can measure of eye-ball (I tend to eye-ball things, lol) the center of the cape. You’ll want to cut the slit from the neck hole, all the way to the bottom of the cape.
Sew Outer Edges
You’ll need to now either zig-zag stitch or serge the opening edges just created, along with the neck. You can also edge the arm openings. Make sure to do the arm holes in a circle and now sew them together. 🙂
