Yep, ardchoille, your correct. Learned this knot over in the desert. Though I don't think the spiral braid with leather would look quite right. Hmm, having a thought...desert tan paracord and light colored leather or denier nylon belt to be worn with my Marpat desert camo kilt that's coming...That might really look good!
But back to the leather. Since I have brown boots and belt and sporran, thought a chocolate leather like I described would look really nice.
