We investigate the solutions of Einstein equations such that a hedgehogsolution is matched to different exterior or interior solutions via a sphericalshell. In the case where both the exterior and the interior regions arehedgehog solutions or one of them is flat, the resulting spherical shellbecomes a stringy shell. We also consider more general matchings and see thatin this case the shell deviates from its stringy character.Comment: 11 page
