Choose your juice carton. Wide
ones work best, but the square
ones are fine as long as you
make them tall enough to fit a
bank card in. Cut off the top
and bottom of your juice carton
and make sure it is thoroughly
washed out.
Fold the sides of your
juice carton down
the middle to make a
valley on each side.
Decide which side of your
juice carton you want as
the outside of your wallet.
Put that side facing away
from you. Firmly fold your
carton into three sections:
2 equal sized and one
smaller (this one is the flap
for securing your wallet)
Unfold your pack
and then cut both
sides off of the
smaller section (the
shaded bits)
With the outside of your
wallet still facing away
from you, cut the edges of
the nearest flap off on a
slight diagonal.
Fold your pack back up and tuck
the flap you just cut into the
opening that was the bottom of
the carton.
The remaining flap is the front of
your wallet. Shape it as you want
and secure it with a rubber band.
