Help with my target please?

[knifethrow3r]

Hey, this is a picture of my target (so far) I want it to be able to stand up on its own and need some ideas for it

It may appear small but the rectangle to the left is 2x3 feet and the board to the right is 12 feet long, and ideas?

can't see a picture stored in your email server.
OTOH, I generally go with a tripod made of 2-3" saplings to hang my axe target from.
another option is to mount a 4' long 4x4 post in an old tire filled with concrete, then lag the target to the post from behind.
