Homemade bow target
So I am in need of a target to shoot my bow. I made one this morning just to be able to try shooting. It was made out of a larger 6 inch thick foam cushion. Works great except my arrows go through it sometimes. I'm standing about 20 yards away, not exactly but fairly close to 20 yards. I was wanting to know if anyone has ever made their own targets. What can you use? How can you make a target your arrows won't go through?
I don't have money to buy one, please don't be cruel. I'm really asking to find out how to make my own targets. I've got 3 regular couch cushions with covers still on them, two different size 6inch thick or so foam cushions, and I've got a zippered bag that a standard size pillow came in more then half full of plastic bags. I also have ply wood pieces and other tools to build. Can someone help? Can I use this kind of stuff for a target? If not what works?
