As has been stated already in the thread, spend the money and buy a bag target. You can get some for under $40 and it is worth the time and work you will spend trying to make targets. Ihave made several myself and the bag I bought is the best. It has probably taken at least 100,000 shots and is in good shape. I replace the cover each year, which you can do with materials from home.

The block is a target that I would not recommend. The two finger arrow removal is BS when the target is new, and when they get easy to remove the target is worn out and getting complete pass throughs. I got one in March and it is already worn out, even my recurve is passing through the target.
