This is a link to the site that got me started. It has easy instructions for the Box and Barrel stitches, and the Cobra stitch (aka Square Knot Sinnet), and also the Butterfly stitch. These four can be very useful for lanyards.
It is important -- nay,
crucial that you learn how to tie some knots for
ending lanyards. This can make or break the look of a lanyard. I make all kinds of stuff out of paracord. I find that the Matthew Walker knot is great for ending anything done with the Barrel or Box stitches (which are virtually the same). There is a knot called a "Terminal Turk's Head" that I use for those, also. It can be done with various numbers of strands. I learned it from a book I bought from ubraidit.com They sell all kinds of cord, hardware, and books and equipment for using paracord
specifically. They are geared toward making horse tack.
Also important to learn is how to neatly sear the ends of the cords. Some recommend using a kind of cutting iron to sear it, but this usually makes a sharp, flat-edged tip on the cord. (Sharp and flat are good for blades, not for cords.) No, you want to get one of those jet-flame lighters that make the blue cone of flame. Hold the freshly cut end of cord steady and touch the flame to it, waiting for it to melt down into a rounded tip. Roll the cord while the flame is on it. Take the flame away and wait about 2 seconds -- literally just two seconds -- and use your two fingers to form the tip a bit, gently plying the semi-solid cord end up toward the end. Use the flame again to get the roundness back. You will find that the cord wants naturally to end in a round tip but it needs a bit of help getting there. It takes about three applications of flame once you're good at it. The reason you wait two seconds is because if done immediately, the cord will give you a blister after melting to your fingertip, and if done too late, it won't be shapeable.
Remember to use more cord than the project needs, because it sucks to be nearly finished and realize you don't have enough, and also because you need some bit of cord beyond the finishing knot in order to make the knot in the first place.
Have fun experimenting and learning.
