Making your composition work in the square format (6x6 common to 120 film used in the Rolleiflex, Hasselblad, and many other cameras) presents challenges to new users who have migrated up to medium format from the ubiquitous 35mm format (rectangular). Whatever format we use as photographers, we are always cutting something out of a larger picture to highlight it. If you are used to this process with a rectangular format, at first you feel limited by a square, until your right brain can accomodate to this new way of seeing. Then you will both actively seek images that naturally fit in the square, as well as learn compositional techniques that allow for placement of pieces of subjects within the square, using the corners. The shot below is an example of how one might fit a rectangular window into a 6x6 cm square using the corners.
