I have appliqued the top to strips of border fabric. I did some applique on the border pieces. I did one by stitching hexes right sides together all the way around, then turning and stitching on the back, much like a facing. I liked this method. Somewhere out there in cyber space are instructions, but I can't find it now. If you are on pintrest it comes up from time to time. Have fun with your hexes!!
