  Weaving frames in separable Hilbert spaces have been recently introduced by
Bemrose et al. to deal with some problems in distributed signal processing and
wireless sensor networks. In this paper, we study the notion of excess for
woven frames and prove that any two frames in a separable Hilbert space that
are woven have the same excess. We also show that every frame with a large
class of duals is woven provided that its redundant elements have small enough
norm. Also, we try to transfer the woven property from frames to their duals
and vise versa. Finally, we look at which perturbations of dual frames preserve
the woven property, moreover it is shown that under some conditions the
canonical Pareseval frame of two woven frames are also woven.
