Echidna Pack Rational

In the upcycling unwanted assignement I decided to make a bag made out of bike inner tubing. These are the tubings that are inflated on the inside of tyres so they are able to be used. The reason why I decided to use this material was becuase in waste bins there was an abundance of these tubings. These were there becuase they were rendered useless becasue they had either been puncutured or they had been worn down and reached the end of thier life cycle.

The other materials that I decided to use were cable ties, old foam that habe been used in plush toys and a rubber material that is used for light waterproofing.

The outer layer of the bag is made entirely from the inner tubing, small squares that were tied together using the cable ties. This is what gave the idea of calling it the echidna pack, the cable ties gave the same kind of effect to the spines on an echidnas back. The back rest area was made out of a larger tyre that had been taken from a small car tyre. I decided to do this because it would be much more comfortable to have less but much larger pieces than to have many smaller pieces touching the back constantly. The straps that were used are just inner tubing that wasnt cut up but left in its initial state.

Once the outer layers of the rubber had been put together I then decided to sew together a inner bag that would be able to hold the things that are placed inside the bag. This was also where the padding was put into the back rest to make it more comfortable for the user to wear.
