This was a purchased unfinished plywood box with a lid, and a Plexiglas insert that allowed a view from two sides.
I covered the exterior with red fleece and trimmed it with ribbon. I made a false angled wall out of foam core board to
hide future wiring for lights on the tree. The interior walls were painted, after covering them with mat board.
I used the same fleece on the floor, and added a fireplace. The tree branches are made of pieces of eucalyptus.
I plan to add flicker lights in the fireplace.

The sister is watching her little brother hang candy canes on the tree, while she holds one to hand to him.
