Another option to remember wiper placement is to put some masking tape or duct tape on the windscreen lengthwise along each wiper when they in their resting position.
Consider putting the comment about getting things out of the trunk at the very top, in case someone follows the instructions before reading that comment.
The fix lasted about a month and a half and then the copper wire broke. I am trying the same technique but this time with a metal paper clip that I had. The paper clip is made of metal that's thicker than the copper wire. I only threaded it through one time and then twisted the ends. One paper clip was enough to fix 2 rivets (both the original one and a new one is now broken as well). I will try to report back if these also break.
You could also just twist the ends of the wire around and around until they are all twisted together, then cut at a length of about 1/2 inch or so and then tuck in as best you can so that it doesn’t stick out.
