Guys, if this is in the wrong section, just let me know where to move it. I am trying to duplicate the targets that our range uses for competitions. I have already made the wooden frame, but I am now trying to find a suitable backing to hang targets one. I have found a couple of options at a local art store, but nothing is large enough to fit the 55"x52" frame. Do you have any ideas on the material that is typically used on the NRA style long range rifle targets and where I might find some large enough to fit my needs? Thanks.
