The study of traversable wormholes is very hot topic for the past 30 years. One of the best possible way to make traversable wormhole is using the thin-shells to cut and paste two spacetime which has tunnel from one region of space-time to another, through which a traveler might freely pass in wormhole throat.  hese geometries need an exotic matter which involves a stress-energy tensor that violates the null energy condition. However, this method can be used to minimize the amount of the exotic matter. In this talk, I will show my studies on the thin-shell wormholes in general relativity in 2+1 and 3+1 dimensions and  heir stabilities. Moreover, I will mention about the thin-shell gravastars  as an alternative model for black holes.
