Abstract
A stitched fabric including a retroreflective core and a yarn stitched through and forming stitch holes in the retroreflective core, where the yarn extends over at least a majority of a width and a length of the stitched fabric but still permits a portion of the retroreflective core to be visible. In some cases, the yarn and the retroreflective core are free from contact by another layer on either side of the retroreflective core. In some cases, a barrier layer is disposed over at least one side of the retroreflective core and a melted portion of the barrier layer fills a portion of the stitch holes.
