Make sure the holes are where the straps will cross on your back. I used scissors to create a hole, and a pencil to make it bigger. You will need to create a hole going through both straps for a screw to go through. Lay them out, and mark where the straps cross. Hold your finger on where the straps cross on your back, and take them off. Adjust the straps so that they cross in the middle of your back, on your spine so the harness will be even and hold the shield in the middle of your back. They should also cross each other on your back. Next, put them on, so that they cross over, and they should clip together across your chest. JUST THREAD IT THROUGH BUT DON'T GLUE IT. IF YOU WANT THE STRAP TO BE ADJUSTABLE, DO NOT HOT GLUE THE END THAT THE FORK PART OF THE CLIP CLIPS INTO. If you want the straps to be a fixed length, do the same to the other end of the strap with the other part of the plastic clip. Thread the strap through the fork part of the plastic clip, and use a glue gun to hot glue the strap to itself, so that it won't come out of the plastic clip. If you want the straps to be adjustable, leave plenty of extra on each strap. If both straps are long enough they should cross over on your front and back. Each strap should be long enough to go from the top of your chest, over one shoulder, cross over your back, under the other arm, and back to your chest. I measured the straps, and luckily they fit me.

I used straps that you can find on bags, two countersunk magnets which can be bought from ebay for about £2-£3 each, a screw with a nut and washers, and plastic clips which can also be found on bags.

It doesn't look totally like it does in the movies, as I haven't used leather or big metal buckles, but I think it still looks good. However, it is the magnetic harness that I designed. I followed the instructable by seamster (credit to him) for most of the making of my shield. I started out aiming to make a captain america shield out of cheap materials that almost anyone could get hold of and use, and to make a shield harness to hold the shield on my back, like cap does in the movies. I've been working on it for quite some time, and for the first thing I've ever done, I'm quite proud of how it has turned out. This is my first project, and it is very simple compared to most things on here, but I thought I'd post it anyway.
