The real star of the show, though, is the tubular nylon the collar is constructed of. Unlike flat woven nylon, tubular nylon doesn’t have an edge, so it’s smooth all the way around. Because the collar is designed for show dogs, the cut ends are sewn to the outside to further protect the coat. The half-inch width is typically partially hidden under Robin’s coat, so the raw edges aren’t visible when it’s on. Unfortunately, it’s not at all reflective, although I did add some minimal reflectivity by sewing some loose stitches with a reflective thread.
