Step 1: Cans
I decided to use RED BULL COLA cans because of two reasons.
First one: i like the colours and their combination in this diagonally way.
Second one: some cans are made out of aluminium, others are produced out of tin-foil (coca-cola). Red Bull uses aluminium. The advantage of aluminium is, that you have no corrosion (rust) at the cut edge and its much easier to cut and to punch!
The disadvantage of aluminium is that its not that ductile, tin-foil is more ductile, and therefore it breakes easier when you start buckling it 2 or 3 times at the same place... but if you act carefully with your suit, this won´t be a problem.
The gloves for this suit aren´t part of this instructable, they have their own and can be found here: http://www.instructables.com/id/LED-Gloves/
Step 3: Tools
Before you start connecting you need holes. Therfore use a puncher or a special bin rail. The hole-diameter has to be larger (1mm) than the grommet-diameter (5mm). This is necessary because the grommets fit better and the pieces stay flexible towards each other. The connection of the pieces works well with grommets (do you call them grommets?). For more solid connections, especially between the can pieces and the steel band, use blind rivets. The steel band helps you to strut some parts like the helmet or the shoulder components.
