TITLE: Undergraduate differential geometry texts
QUESTION [25 upvotes]: Can anyone suggest any basic undergraduate differential geometry texts on the same level as Manfredo do Carmo's Differential Geometry of Curves and Surfaces other than that particular one?
(I know a similar question was asked earlier, but most of the responses were geared towards Riemannian geometry, or some other text which defined the concept of "smooth manifold" very early on.  I am looking for something even more basic than that.)

REPLY [5 votes]: There is our book What is differential geometry: curves and surfaces.
It is written for those who either plan to work in differential geometry, or at least want to have a good reason not to do it.
