Glad you asked...
Parachute cord bracelets are braided paracord, or similar 1/8" diameter cord and can be made as jewelry, or in larger projects for pet collars. Because the braids do not stretch, it is helpful and easy to include a buckle. For details on making a paracord bracelet with a side release buckle, see this link. http://www.instructables.com/id/Paracord...
Then again, this answer might help you...
You can make parachute cord bracelets just by taking the cords and braiding it like you would you're hair. Then at the end you just tie a knot in the end and burn it so it won't come apart.
