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
Step 2: Cut the pieces
Cut 1 piece : 32 cm X 20 cm
Cut 2 pieces : 9,5 cm X 20 cm
(the bigger measures in the "vein" direction)
With a pen and the ruler:
Piece 1: Make lines with pen in the bigger side: 5 cm + 8 cm + 7 cm + 12 cm.
Piece 2: Make a line in the middle of the bigger side (10 cm + 10 cm)
Force the pen in the lines to easy to fold.
Step 3: Fold
The line central in a opposite manner to parallels lines .
The central line form the back of seat. The part that measure 5 cm is a front base and, the 7 cm and the 12 cm together form the back part of the sofa.
Fold the piece 2 (2 pieces) in the middle
Step 4: Make soft
In the big piece, cover with sponge or cotton the seat and the back parts. Use a little more to cover part of the back support as show in photo.
Step 5: Cover
Step 7: Assembly 1
Put glue in the 7cm part (back seat) and then, join with the 12 cm part as show the photo
Step 8: Assembly 2
Make the same thing with inferior front part in the central piece and the lateral and hold on. If you use the PVA glue, fix the parts in the right place with tape and wait dry.
Step 9: Assembly 3
Turn on the sofa (down inside).
Fill the junctions with glue (this reinforce the structure of the sofa)
For make the structure more strong, put zigzag strips inside the empty space as show the photo.
Cover the base with paper.
Step 10: It is done!
Maybe, if you increase the thickness of cardboard put together many foil, you can this sofa in a non scale size. You can reinforce the inside like a show in the doll sofa or use some strips of wood.
There were many thickness of cardboards. Cardboards used to packing dippers or refrigerators are more resistant.
PS:- I don't know the right name of certain things. I live in Brazil and my native language is portuguese. Please, if I used any wrong name, help me.
Thanks and sorry about my English
