Here is another paracord bracelet I made for a co-worker and fellow geocacher last night and I also redid one I had done before.
The top one is one I have made previously as comparison.
The middle one I posted a picture of before, but I was not happy with the way it looked, so I took it apart and redid it over the weekend. If you decide to use this pattern, pull it as tight as you can as you weave it back and forth, and when you think you have it as tight as you can, pull it a little tighter. That makes the pattern come together nicely and look more uniform. This one is the same length as before, but I pulled about 12-18 inches of slack out of it. Not wanting to waste that, I spiral wrapped down the full length. I think this added a nice touch to the pattern.
The final one is the one for my coworker. She has a considerably smaller wrist than me, so this a full 1 1/2 inches shorter. This one uses about 9 feet of paracord.
Here is the ratio I came up with:
The 3/4 inch wide buckle will add an inch. Taking this into account, subtract an inch from the final size you want (in inches), then multiply this by 16.5. This will give you the length in inches of paracord to use. You should plan to made the bracelet a little larger to give you a little room to fasten the buckle without pinching some skin when it snaps. You do that only once....
Keep in mind that I run four strands through the center rather than two that most of the patterns show. This fills the buckle nicely, gives a fuller feel to the bracelet and gives you additional cord to use if needed.
I will tie these pretty much as tight as I can, pushing the knots up frequently. It will be pretty stiff when you first finish, but after wearing them a while, they will soften up.
