Quasiopenness seems to be generic to multi-field models of single-bubble open inflation. Instead of producing infinite open universes, these models actually produce an ensemble of very large but finite inflating islands. This effect could have a signature in the temperature anisotropies of the microwave background. In this paper we study the possible constraints on existing models of open inflation from the absence of such an effect. The combined effect of supercurvature and semiclassical anisotropies make some models incompatible with observations, and severely reduces the parameter space of others.
