Abstract
A radiopaque tell-tale filament is disposed between two plies of a multi-ply surgical sponge in the quadrangular area defined by the stitched or folded edges of the sponge and an inwardly disposed continuous stitch. The ends of the tell-tale are embedded in the stitching but the intermediate portion of the filament is otherwise freely disposed in the quadrangular area.
