Paracord is lightweight nylon kernmantle (string woven around a string core) cord originally used as parachute cord. Sturdy and light cordage that does not rot when exposed to moisture is phenomenally useful, and this collection contains some of the clever applications for paracord created by Instructables authors.
For those of you who don't care about the technical/history stuff, paracord is the best of string and rope combined in one colorful package.
You'll need four strands of about 3 meters each to make this woven bottle wrap. Less if you elect not to build in a handle. The pictures are very easy to follow, and there are several examples of successful reproductions in the comments.
Learn to wrap tool handles from Harlan Whitman's beautifully photographed project. He's a little loosey-goosey when it comes to exact measurements, but "use more than you think you'll need" is pretty good advice when it comes to cordage.
If you've got 100' of spare paracord, this belt project might be for you. This project is presented as a photo slideshow and may require some back and forth between pics and the text, but the photos are very clear.
Tired of getting your paracord bracelet sizes wrong? Try this cheap and easy paracord jig. You'll need a yardstick and a saw. If you figure out an alternative to the miter saw that the author used, sound off in the comments.
Cover your headphone cable with paracord for that premium cloth cord look and feel.
You'll need to be comfortable cutting and reattaching the headphone wiring, so be prepared to do some light electronics, too.
"I was able to make this paracord fid in about 15 minutes with little effort and for under 80 cents. In addition, these fids do not require you to cut the end of the paracord at a 45 degree angle before inserting the paracord - just lightly singe the end first."
