In Memory of my Father Vietnam War Vet Patch measures 3.5×2 inches and is embroidered in Black / White / Green / Red / Yellow. You can sew this patch on your leather or nylon jacket. It features die cut borders for easy sewing. We also have treated the plastic backing of this patch with heat activated glue. You can also iron on this patch to your clothing. The plastic iron on backing not only gives you the capability to iron on the patch, but it also helps keep the stitches together over time.
