  We present a method of construction of exact localized many-body eigenstates
of the Hubbard model in decorated lattices, both for $U=0$ and
$U\rightarrow\infty$. These states are localized in what concerns both hole and
particle movement. The starting point of the method is the construction of a
plaquette or a set of plaquettes with a higher symmetry than that of the whole
lattice. Using a simple set of rules, the tight-binding localized state in such
a plaquette can be divided, folded and unfolded to new plaquette geometries.
This set of rules is also valid for the construction of a localized state for
one hole in the $U\rightarrow\infty$ limit of the same plaquette, assuming a
spin configuration which is a uniform linear combination of all possible
permutations of the set of spins in the plaquette.
