Spinal Paracord Bracelet Tutorial by Yuuma

I made a tutorial of this bracelet i call Spinal, i learned this knot from my grandmother, she used to do macrame. She gave me a drawing that explains this knot. I do not know the name of this knot and I have still not seen a tutorial. If anyone knows the name or has seen an tutorial let me know so i can give credits. I saw afterwards that the focus of the camara was not quite right, sorry about that I currently do not have time to make a new video. For this bracelet I used a 3, 8 mirror black finish gun
