  We give a sufficient (and, in the case of a compact domain, a necessary)
condition for the embedding of Sobolev space of functions with integrable
gradient into Besov-Orlicz spaces to be bounded. The condition has a form of a
simple integral inequality involving Young and weight functions. We provide an
example with Matuszewska-Orlicz indices of involved Orlicz norm equal to one.
The main tool is the molecular decomposition of functions from a BV space.
