ABSTRACT:
An item of luggage includes a rigid, generally rectangular luggage body having rounded corners, and a pair of generally rectangular, flexible walls which engage opposite sides of the luggage body to define the luggage interior. The corners of the flexible walls are cut to form notches, and a section of flexible, resilient material is sewn into the notches in a manner causing the section of material to form a three-dimensional, contoured shape having an edge which can be placed against and sewn to an adjacent rounded edge of the luggage body. PVC piping is sewn between the flexible walls and the luggage body and section of flexible, resilient material to give the luggage a pleasing appearance and to help strengthen the corner construction.
