This has worked well for me. I just used old shirts and other clothes that I or my family hadn't worn in a long time. I used a large cardboard box.For field tips go to IFA and grab some of the ploy feedbags and just jam pack them with cloth(cloths, blankets, sheets). I double bag it for a little more durability. when it gets too shot out to hold stuff in you just put it into a couple new bags and add cloth to fill in the shot out space. One word of caution is DONT USE JEANS. Besides the zippers and buttons arrows are rally tough to pull out of the jeans.
For Broadheads I would check out the blob targets. They are a up there with the higher end targets but are far bigger and last longer. My current blob has been around for 4 years of broadhead abuse and still works pretty good. That is 3 years longer than any of the others I have had.
