A planar graph is inscribable if it is combinatorial equivalent to the skeleton of an inscribed polyhedron in the unit sphere \(\mathbb {S}^2\). Giving an inscribable graph, in its combinatorial equivalent class if we could also find a polyhedron inscribed in each convex surface sufficiently close to the unit sphere \(\mathbb {S}^2\), then we call such an inscribable graph a stable one. By combining the Teichmüller theory of packings with differential topology method, in this paper we shall investigate the stability of some inscribable graphs.
