Laminations are models for locally connected Julia sets of complex polynomials. This paper is concerned with laminations associated with degree 3 polynomials. We introduce and discuss simplest laminations and prove that subject to certain conditions a finite collection C of periodic polygons is associated with a simplest lamination L_C. This lamination is unique with respect to some collection of pullback schemes. We apply this result to the case where the collection C consists of the orbit of a periodic chord. We then introduce and characterize simple Fatou gaps by their boundary leaves and discuss the relationship between simple Fatou gaps and identity return triangles.
