You can flip over the template and reuse it to make a symmetrical second armor piece. I would like to point out that whole parts like the gauntlet, shoe, shin, thigh, bicep, handplate, shoulder and maybe some others only appear once in the template. Like this: b -> d It's a mirror image of the original. It just means to trace it on one side then turn the template over and use it on the opposite side to make another trace on the foam. I admit the 'Flip x2' is a little confusing. Some of the edges will get cut off if you use anything other than US Letter, but honestly as long as you have the basic shape, you can guess the bit that gets cut off. I used US Letter sized paper for mine, but you could probably use a4 just make sure to use the original image size when you print and don't convert it to a4 or it will shrink the template to fit the different paper.
