Needed to replace my last DIY target. So here is how I did it. These are signs that are corrugated plastic. You can get it at your local sign shop or see if the coke guy has any he is going to throw away. I first bend the signs in the middle. I cut up some plywood old stuff I had laying around. Old pallets what ever you have. I then staple it to the corners.
Then cut some more supports for all the edges and staple them in. forgot to mention I cut this one in half 15" deep and got 2 targets out of it. Once the supports are in I use house wrap as a facing folding the edges and stapling it to the supports keep it tight. Then start filling I used old clothes with no buttons zippers. Plus the layer in between is plastic wrap here is a rope handle drill into the support and tie inside
more filling and then another layer of clothes comes after that. Second facing goes over that. Some plywood to flatten it with weight. Then pull tight and staple to the supports Done. Then a point blank shot and its good. Two finger pullout. Yeah I like that!!!
Oh I forgot to mention, The paint does wear off fast I just use red dot stickers or some thing on that lines. This target is 2 years old now and works well
