Mow your lawn square with your house on week one. Week two, mow at a 90
degree angle to what you mowed last week. This is the simplest method
to striping your yard.

The major league fields are mowed in this fashion as well but most of
the time they are mowed twice on the same day to achieve the look you
see on television, once in the morning and then again in the afternoon
before the game.
