RE: Cheap traditional substitutes.....
I second Chessbum for MS tomato stakes for arrows. I use em mostly for stump shootin.
I second John for cheap glue. Gonna try the toilet wax.
I go to the local grain and feed store and pick up some of the empty grain sacks and fill them with rags and plastic shrink wrap or plastic bags for targets. Cost about one gallon of gas for several targets. Side benefit is I get to pic up a few primary turkey and goose flight feathers.
