Purse

Take the tetrabrik, open the 4 corners and flatten the tetrabrik completely. Then cut the upper and lower edges following the preformed fold. You now have a rectangle of 12.5 cm x 13 cm open on each side. Rinse the tetrabrik well so that it is completely clean. Let it dry thoroughly.
Then fold the brick into three equal parts lengthwise. Cut in the upper part the front side and the side parts so as to keep a flap that will later serve as a flap for your wallet. Fold the side parts of the lower part towards the inside (part 2 and part 3) while carefully delimiting the outline of your wallet. Then fold part 3 onto part 2 and glue them together with glue or double-sided adhesive tape.
Finally glue the Velcro on the inside of the flap and match it to the Velcro you will stick on the outside of the wallet. Check one last time that it closes properly and put all your coins in it.
 
TIP : To make your wallet even more fun you can use wrapping paper and / or coloured adhesive tape and a button as for closing as a finishing touch.
