Just to let you know....this is how I did mine.
A friend made me a ...somekind of cabinet.
I brought to the taxidermist the top of the cabinet....what he did, is...
1 - he mounted the deer head like he usually does.
2 - then he used and " L " shape metal plate to screw the back of the deer
3 - then he screw it on top of the wood top cabinet.
4 - He was able to put somekind of wild mushroom and branches to cover it up.
I can take off the top of the cabinet....(in green) off anytime so I can move the whole thing around if I want.
I wanted something different than having it on the wall.
