“…al. presented a solution [7] where a straight cosmic string decay into conical surfaces at its end points and ending up as a stringy sheet with radial strings. This solution can be extended to the other cases [8] including a string changing into a cylinder, a cylinder changing into a cylinder with different radius and a cylinder decaying into conical surfaces at its endpoints and ending up as a sheet with radial strings.…”

We investigate the solutions of Einstein equations such that a hedgehog solution is matched to different exterior or interior solutions via a spherical shell. In the case where both the exterior and the interior regions are hedgehog solutions or one of them is flat, the resulting spherical shell becomes a stringy shell. We also consider more general matchings and see that in this case the shell deviates from its stringy character.
