Here is the shot of the base of the Pooh tree with the door frame and fake door attached. The door is just made out of some bead board and 2◊2ís.
Here is a closeup of the Pooh Door.
Here I am measuring the strips of polystryrene that I will be using to create the tree trunks.
Here I am cutting the polystyrene with a dremel tool. I later found out that it works much better with a jigsaw.
Here you can see how I am glueing the strips of polystyrene to the frame to create the tree trunk. Later I will carve the polystyrene to make it look like an actual tree.
Here you can see I used some long screws to help hold all the polystyrene together. I will glue one more layer on top to hide the screws.
