  In graphite crystals, layers of graphene reside in three equivalent, but
distinct, stacking positions typically referred to as A, B, and C projections.
The order in which the layers are stacked defines the electronic structure of
the crystal, providing an exciting degree of freedom which can be exploited for
designing graphitic materials with unusual properties including predicted
high-temperature superconductivity and ferromagnetism. However, the lack of
control of the stacking sequence limits most research to the stable ABA form of
graphite. Here we demonstrate a strategy to control the stacking order using
van der Waals technology. To this end, we first visualise the distribution of
stacking domains in graphite films and then perform directional encapsulation
of ABC-rich graphite crystallites with hexagonal boron nitride (hBN). We found
that hBN-encapsulation which is introduced parallel to the graphite zigzag
edges preserves ABC stacking, while encapsulation along the armchair edges
transforms the stacking to ABA. The technique presented here should facilitate
new research on the important properties of ABC graphite.
