An example method for providing a flexible base structure for a portable shelter includes the steps of forming a continuous loop of a flexible material and attaching a plurality of rib intersections such as grommets at respective locations along the flexible loop. An alternative method for constructing a flexible base structure for a floorless portable shelter includes forming a continuous loop of a flexible material and arranging a plurality of openings at respective locations along the continuous loop. An embodiment of a base structure for supporting the ribs of a portable shelter includes a flexible loop and a plurality of rib intersections arranged along the flexible loop. Each of the plurality of rib intersections forms an opening for receiving a respective end of a rib that supports the portable shelter.
