...made this for my friend Sgt. Mac, uses 12' +/- and no buckles (6' per color). I pre-shrink the cord on bracelets, you should too! I kept three cords on the inside to give it a little girth, this is a man's bracelet after all. standard cobra stitch. did one like it before, but used only two strands inside. it was for my son who is 8.

Nice bracelet. I've made a couple myself, but still don't know how many feet of paracord you use for each inch of wrist contour. any tips? Thanks

not certain on a per inch calculation; I just pull out 15' of cord for a bracelet and usually use 10'-13' of it.
