This is a repost from a recipe I posted on r/archery:
Been experimenting with diy targets for a while. This is one made out of a 50x50 cardboard box filled with stacked cardboard.
I alternated cardboard scraps with thightly fitted peaces to press them down.
I finished them up with a U formed piece that sticks tight and prevents the pieces beneath to come out on top.
The benefits of this is that I can just swap out the box (have several) reuse most of the filling. Also it is cardboard only, no glue or else, which means it is still fully recyclable.
After some arrows thrown at, it I'll probably put some flat pieces to the back.
Apart from that it works great so far
It probably needs to be a bit thicker for bows above 30 lbs. Currently it's 15 cm thick.
However a foam target will probably be better. This is meant for beginners who just starting out on a home range.
I have a second target, which is a burlap sack filled with plastic wrappings. It's also good
Mmm, at 35lbs I'm putting holes in the plywood behind my 8cm foam now ... I should probably chuck some cardboard back there just to make it last a bit longer
