Systems and methods generating textiles with repeating design elements based at least in part on Voronoi diagrams are provided. In one example implementation, the method can include generating a plurality of seed points in a graphic area. The seed points are utilized to create a Voronoi diagram. A Voronoi diagram is thereafter propagated within the graphic area based upon the seed points. The method also includes receiving a first user input defining a design area. The design area includes a plurality of boundaries within the graphic area. The design area is then correlated to a textile segment and a textile design is generated by replicating the cells in the design area. The cells that intersect the boundaries of the design area are replicated with identical instances placed at the adjacent sides of the design area and the corners of the design area.
