Afterwards I inserted one end of the twisty through the gap cape's lining where the neck chain is located and pushed it all the way to the end. Then I inserted the other tip of the twisty through the other side of the hole, lining up with the chain inside around the back of the neck all the way through to the end of the cape.
One of the hurdles I had to go through was mess up some of the stitching because my BS Vader's cape had some of it blocking the wire from completely reaching the edge of the cape's lining due to those weird corner pieces it has at the end of each side. I basically cut off some of the stitching using an X-Acto knife and put a dab of superglue at the required parts so the stitching won't come undone. The glue shouldn't spread onto the cloth that severely since this only usually happens at the very far corners of the cape where you still have those triangle-shaped corner pieces to keep the cape tips solid.
