My older two boys share a room and sleep in bunk beds. Since we moved them to bunk beds it's been great as it has opened up a ton of space in their room for quiet time away from the chaos of the rest of the house. I love bunk beds.
We cut the log (landscape timber? )into 3 parts, used socks from the dollar store for the hats, cut the nose chips out of wood and material of choice for scarves. Buttons hot glued down the front and paint for eyes and cheeks.
