From day one in my preparedness journey, I have been enamored with paracord. I carry it with me at all times, in the form of a key ring, bracelet, lanyard for my emergency whistle, and as a leash for my dog. This stuff is really strong and has so many uses that I stopped counting long ago.
Most of my paracord do-dads have been purchased, but a couple of years ago I learned paracord braiding myself, and even with my not-so-nimble-anymore fingers, did a darn fine job creating paracord bracelets. A 100 foot hank of paracord will cost you less than $10, so why not learn to craft paracord items yourself?
