thought I'd share this, even though it probably won't work for a lot of you. I took a seed sack and filled it with baling twine and sheep wool(right off the critter). Neighbor has several black fleeces that have no value. Anyway I packed it as tight as I could using about 50/50 of each. I put the wool around the edges and filled up the center with the twine. Actually the new net wrap you see on the big round bales works better than twine, but twine will work if you get it good and tite. Sew up the end of the sack and you're done. Probably don't want to bring in the house as wool has a little odor until it's been degreased. When bag starts to wear out just find another and shove the old target into it. One fleece will do about 2 targets depending on the size of the sheep and the target size of course. Arrow only penetrate 3 or 4 inches and then just hang.
