stopped at a grain and feed store. They had nylon (plastic) woven feed bags. They are 18"x 28" for 35 cents each. The last one I used  lasted about a year(single bag). So this year I double bagged.I used the stuffing from a bag target I purchased. After I fill the bags I roll the top shut over a piece of rope and then put small tie wraps through the bag to hold it shut and secure the rope. I then tie the bag up with the rope. I shoot almost every day so the target gets quite a few arrows shot int it.

I use the same idea but stuff it with Wal-mart bags.

I bought one of those eternity targets an eternity ago. I just unwrap the top and smoosh it down replace the bag and tie it back up with hog rings or bailing wire.  I don't see how I could ever wear it out.

Old carpeting that is disposed of makes a perfect arrow stop/target.The carpeting that I have found is usually cut into 4' by 10' lengths, give or take. I gather these up and have made a support that is 4 ' wide and about 5 ' high that I place the carpeting onto. Multiple layers of the carpeting lasts a long time and stop the arrows without damage.

My targets are all "targeted" by the local bear population...my 3-D was demolished, my bag target ripped to shreds. Feed bags are about all I can use and still stay in my wife's allowed budget...lol.  

Where I work at we use these nylon Tote's for overspill.  I got permision to take one and stuffed it in my burlap u-stuff it bag and man, arrow goes in an 1" and that is it.  Had few buddies over and we put about 1,000 arrows in it and it is still fine.  Alot of places that get pallets or tote's stuff like this have a nylon printing wrap around them, same material, check local places, everyone usually throws these away.

The only problem I found with poly bags is that UV eats them up. They seem to deteriorate pretty quickly if left out in full sunlight. I have used them many times though.
