Terminology - Square Base

There are a number of bases that starts off an origami.  We are gonna be focusing on making flower balls, and they use Square Base as the foundation of every fold.

There are a few ways of making a Square Base.  I'm gonna be illustrating one of the many ways here.  (Some are just better explained through video.  Hopefully I'd get to it one day... ^^)

Please note:  The illustrated Square Base is folded with the coloured side down.  Depending on the design of the flower ball, we may have to start off a Square Base with the coloured side up.

Here it is:

Step 1:  Start with a square paper.  Valley fold diagonally along the dashed line to form a triangle.

Step 2:  Valley fold it in half along the dashed line to form a smaller triangle.

Step 3:  Take one flap and Valley fold it in half.  Crease well.  Two Valley fold is created from this.

Step 4:  Squash fold by open out the top flap to the right along the new crease line.  The Valley fold on the left sits nicely into the fold, but the one on the right doesn't.  Re-fold the crease to create a Mountain fold.

Step 5:  Squash paper down neatly along the crease line to form a square.

Step 6:  Flip the paper over.  Fold along the dashed line.

Step 7:  This is a repetition of Step 3.

Step 8:  This is a repetition of Step 4.  Another Squash fold here.

Step 9:  Square Base.

  That's the Square Base.  Easy and fundamental to our flower ball origami.  ^^
