What could I use for a back stop for shooting in my garage? My daughter is in 4h archery and I want to get her shooting more and if we could shoot at home that would help a lot. She is shooting a Mathews mission craze at the lightest setting and shortest. Would like something that will stop the arrows without breaking them. She can be inconsistent and miss targets so I want to put up a backstop to not be punching holes in the walls and breaking arrows.
