First find a small plastic stag/deer. This one came as a cake decoration but you can look in cheap plastic animal sets for children.
Cut a wooden shape for the backboard out of Balsa wood. Balsa wood is thin and easy to cut using a craft knife or even small scissors.
Stain and varnish the wood.
Cut the head off the stag using a sharp knife. (This feels a bit mean even though it's plastic!!)
Paint the stag using acrylic paint. This takes away the plastic look.
Finally, glue it to the wooden board and put onto your wall.
