I will show you how I made a wide paracord bracelet with a side release buckle. This is also a good plan for a collar for you dog.
Step 1: Pick your colors
Also for your side release buckle I recommend a 1" size. This allows you plenty of room to insert the cordage. The 5/8" size I used just made it very tight to work with.
To figure out how much paracord you will need, measure your wrist where you want the bracelet to sit at. Take that measurement and multiply by 12 to get your approximate start length. You should have plenty of cord left over at the finish. It's better to have too much than not enough.
The color you want as the outside one should be your wrist measurement times 12. You should make 2 lengths of this. The color you have for the inside will be twice as long as the outside color or 24 times your wrist measurement.
Loop the strands onto your buckle using a cow hitch knot
One tip is to make sure you keep the same pattern going and not switch which cord goes over and which one goes under. If you do switch the order it will make the pattern look disjointed.
Step 2: Step 1
Snug up the half knot.
Step 3: Step 2
Tighten the half knotup to the base of the previous knots.
Step 5: Step 4
Tighten the entire knot up snug.
Step 10: Step 9
This step connects the two seperate rows of square knots together.
When you repeat this crossing for each set of knots, remember to always cross the cords in the exact same way. It makes the resulting bracelet a lot more neater looking.
Step 12: Attaching the other side of the buckle.
What I normally do is use a cow hitch with cords 2 and 5 onto the bracelet and then as I am knotting the rest of the bracelet these ends are doubled back on themselves and knotted over so they stay snug and secure.
Step 13: Finished
One tip: When you are nearing the end, have whoever you are making this bracelet for try it on. If it is too tight or loose it is easier to make adjustments now rather than after you have cut off the excess cord and melted the ends together.
