Better late than never!!!
A piece of old carpet is a good back drop for arrows with blunts or field points but not for broadheads.
Get as many thoughtful shots as you can between now and hunting season but concentrate of each shot as if it were the one at Mr. Big.
If you want to have a narrow arrow pass you can use a floppy rest. I use them on most of my bows and love it.
You can see one here on this bow
these are the how to directions that Mickie "the ferret" Lotz sent me on how to make a floppy rest.
