When joining cardboard together there are a different variety of ways to do it, as this chair has to be made entirely of cardboard and no fixative can be used I will be exploring the different methods and identify the best! I will also have a brief look at any fixatives for reference.

Creasing.
When working with cardboard you need to create a bend to finish off your product, the neatest way to do this is to cease the cardboard. it also retains some of its strength as you are not creating a joint out of two pieces of cardboard. To do this you will need;
 1. Cardboard
 2. Ruler
 3. Pencil
 4. Blunt Knife

1. Using the ruler and pencil, draw your crease line on the cardboard.
2. Take the blunt knife and the ruler gently go over the line creating a groove in with the cardboard will bend along.

Originally used as a liner for tall hats it became more used as a shipping material in 1871. In the beginning wooden boxes were used which was vey heavy but provided great protection, when corrugated cardboard boxes started to be used it gave the same level of protection but made the packaging so much lighter decreasing the shipping cost. As the cardboard is about 10th of an inch thick it took up less space than that of a wooden shipping box meaning more items could be shipped.
Corrugated cardboard has two smooth outer pieces of cardboard that protect the inner corrugated card, the corrugated medium in the centre provides air columns which act as a cushion to prevent any damage.

Advantages Of Corrugated Cardboard:

• Corrugated Cardboard is light weight.
• Inexpensive and therefore widely available.
• Corrugated Cardboard Boxes have better printing and graphics capabilities..
• Corrugated Cardboard available in many different sizes and thicknesses.
• Corrugated Cardboard is completely recyclable in nature that makes them eco-friendly
• Strength

Disadvantages Of Corrugated Cardboard:

• Not great for use with heavy items
• Under extreme pressure or on stacking, Corrugated Cardboard may get deformed
• Poor moisture tolerance
• Requires protection from insects and pests

*Cardboard has similar properties to that of wood. It is an anisotropic material (strong dependant on the direction of use). The strength of cardboard depends mostly on the material structure and on the raw material composition. It can be either from virgin fibers (VF) or recycled fibers (VF). RF have less resistance to moisture than the other.

Cardboard is the generic name given to any material that is a multi-layered paper product, using adhesive between each sheet making the material relatively sturdy.

There are various types of cardboard and the most thought about is the ‘corrugated card’ which involves two sheets that sandwich a ‘filler’ in this case an intestine like design. This leaves a piece of cardboard with smooth sides and added strength due to the internal corrugated piece. Used mainly in shipping boxes as it is sturdy and gives a great amount of protection.

By using only one or two sheets of cardboard you can create a much simpler type of box used to build gift boxes, due to the softer nature of the cardboard these are not suitable for shipping as they will easily break.

You can use really thin sheets of cardboard or heavy paper to generate mock up models of furniture or even buildings. This is an inexpensive way to express your ideas without committing too much.

It is widely recycled and as it is made from recycled paper then its great for the environment.

For our chair we are using corrugated card as it has a good amount of strength and you can do a great deal of different things with it.
