First, the wood to make paper is planted for , nobody is destroying the forest to make paper.
When you use wood, a tree die. Many times, you have a wood piece that was knock down illegally...
Paper materials can be recycle!
My kids played in cardboards doll houses, I make a ballet scenery with cardboard (it is more light). It is easy to cut. I love cardboard material!
You can make this in others sizes, even a normal scale (use united cardboards with a thickness about 2 cm -1 inch)
Step 1: What you need:
Old cardboard box
A hand saw
Hot glue or PVA glue (spend more time)
Clips that you use to dry clothes (sorry, I don't know the name in English)
Fabric enough to cover 3 pieces (a strip of 30 cm)
Plastic sponge or cotton wool
