take a piece of 1x2 and cut it two two feet...then hold the chicken wire to the wall on one side and screw the 1x2 over it to the wall...am I making sense so far?...then just stretch it across the closet and do the same to the other side...that's what I would do...if you ever need to move the screen two screws and off of one side and off it comes...whatcha think?
