Im trying to build my own archery target. I know thereīs alot of talk about the materials that can be used to go inside as the stuffing... Cardboard, old clothing, old sheets, foam... I even came across "plastic" one time. The thing is, Iīve also read that there are some things that, with time, can damage the arrows or even bend them. My question is, whatīs the best? What are some "dos" and "dontīs"??
