We prove that any Legendrian knot in (S3, ξstd) bounds an exact Lagrangian surface in ℝ4 \ B4 after a sufficient number of stabilizations. In order to do this, we define Lagrangian projections, consisting of a knot projection along with some additional information, and construct a family of combinatorial moves which correspond to Lagrangian cobordisms between knots.
