I report studies of several novae which are known or suspected to be recurrent. I will discuss our early morpho-kinematical modelling of the evolution of the optical spectra taken after outburst for two recent novae. In addition, in the case of the known recurrent nova RS Ophiuchi, this is also coupled with HST imaging. Results suggest that remnant shaping happens very early in a nova outburst and the geometries of the nebular remnants are derived. Overall, these results emphasise the need for coordinated imaging and spectroscopy if we are to truly understand remnant shaping in these systems together with the wider implications for studies of shaping mechanisms in other astronomical objects.
