Hey TX I started with about three months worth of the plastic grocery bags,then wrapped them in a foam bed comforter,and lastly used a tarp and wrapped the tarp around all this.,The other day I started shooting arrows into it and found that my arrows where going in a little farther than I like so today I took it apart and added some old blue jeans and some old clothing.After adding these I again wrapped the foam bed confforter around all the bags and cloth and duct taped the foam comforter around .Lastly I used some nylon cordage rope and threaded through some of the eyes.The blue one on the ground on the right I simply used duct tape and it rejuvinated an old broken down bag target that I had.These tarps work great for doing this.
