  We present preliminary calculations of electron scattering polarizations from
models of structured cool star envelopes. We note that net polarizations from
unresolved sources can result from non-spherical scattering envelopes and/or
anisotropic illumination from a photosphere that has brightness variations. The
resultant polarizations are quite small (hundreths of a percent); however,
Rayleigh scattering from molecular opacity and/or dust scattering from the more
extended envelope under similar considerations may produce higher
polarizations.
