  Models with closed FRW cosmologies on the worldvolume of a constant-tension
brane inside a black hole provide an interesting setup for studying cosmology
holographically. However, in more than two worldvolume dimensions, there are
limitations on such models with flat spatial slices. I show that these
limitations can be avoided by considering instead hyperbolic slices. This also
naturally makes contact with previous work on Euclidean wormholes.
