High quality spectropolarimetric observations of supernova are becoming increasing available and provide a powerful way of exploring the asphericity of such events. Here we present some theoretical studies aimed at increasing our understanding of how features appearing in a polarization spectrum give insight into the supernova geometry. We focus our attention on a single spectral line, and explore how various 3-dimensional distributions of line optical depth and electron Thompson opacity produce different polarization line profiles. In particular we calculate the polarization due to clumpy and jet-like geometries.
