A simple slim wallet made from 1L Tetrapak carton commonly used for milk products - the only things you'll need are scissors or a craft knife, a hard edged object to crease edges with and a 1L Tetrapak carton that suits your design fancy. This wallet requires no glue, adhesives or tape.
It should take about 3 minutes to make an extremely practical, durable and waterproof wallet that looks better as it gets older!
Step 1: Choosing your design
Rinse well and dry the Tetrapak carton before starting to ensure no residue remains in the carton.
Open the top of the carton fully.
The most important step is organising how the wallet will look when finished and this is the first decision to make.
You will need to choose what face of the carton will be on the outside of the wallet and which will be on the inside. With the carton standing upright choose a surface that will be the outside (the one that everyone will see and comment on), the inside face of the wallet will be the surface directly to the right of the wallet's outside face [see picture]. The other two faces will not be seen, but will be used for folding and will make the wallet more durable.
