guess its pretty heavy then
I wouldnt use sticky anything as its bound to end in tears
You either buy an invisible mounting bracket, where you screw a rail to the wall and mount a hook or hang over thingy on the back of the door and lift it on, but all the weight is on the door
or you get or make some U shaped brackets for the bottom, and then use a mirror mount at the top to keep it in place, but then all the weight is on the wall, not on the door
