Okay, since we don't want to damage a wedding ring I took a colored paper clip and replicated the shape of a ring about size 5 or 6. I looped it and then cut off the excess, put it into a nock of an old CX 200 shaft. Placed it in a ground support, 2' away from the face of my target background. The object is to, shoot your arrow thru the center of the loop, catching the loop and leaving it on your arrow shaft.
It will be nice if you can video the shot, but still pics are okay too.
Good luck!
Remember its all in fun.
