DOUBLE DIAMOND LETTER FOLD

The Double Diamond Letter Fold is really quite easy to fold although it may look deceptively difficult.   Here is the crease pattern.

The marker creases, shown in grey on this diagram, add to the charm of the model so there is no need to make them soft. 

RIBBON BOW LETTER FOLD - Part Two

I tried out the Ribbon Bow Letter Fold on an A4 sheet

 And a sheet of American Legal sized paper.

Both of these paper sizes works well with this model.  The longer the paper, the longer the straight section at the end of the bow "loops".   I particularly like the effect with the legal sized paper which is the one to use if you want to write a looooonnnnng one sheet letter to a friend or lover.
