You can start with any kind paper with a square size.

Here the back side of the paper is shown.

front side of origami paper

This is the front side of paper.


It is somewhat shinier compare to the back side.


crease pattern of origami balloon base

The crease pattern (CP) for balloon base is shown on the left.


The order of folding is

(1) two valley-folds followed by

(2) two mountain-folds.


The following steps #1 through #8 explain these folding in detail.


The CP for balloon base is exactly opposite of the one for square base. If you switch between valley-fold and mountain-fold, then you can switch the base.
