Whipcording

Come
here! I want to teach you something!

Many braiding and weaving techniques have been used
throughout history to turn thin threads into stronger cords. Most people in the
SCA are familiar with the cords that can be produced through fingerweaving and lucet work, but
there is a less commonly known type of braiding that may have been used in
Bobbins
Bobbins may be as simple or as fancy as you like. For demos and classes, I use wooden doll-style clothespins. For my own use, I use turned wood items that can be purchased at your local craft store. My current favorite is a doll or angel form, but other options include candlesticks, curtain finials, or a combination of pieces (like a Shaker peg plus a doll head). Round items are best as they avoid tangling and you want a bobbin with a weight comparable to the item you are weaving (i.e. thin threads can make do with little dolls, leather or heavy cord will need more substantial bobbins). I have a special set made for me by a local wood turner that are beautiful and satisfying to work with, but more ornate than necessary for the beginner.
Strings
Choose natural fiber threads if at all possible, cotton and linen are the easiest to work with. Silk makes a beautiful braid, but can be slippery, and wool can result in a springy cord that requires heavy bobbins to control. Usually, whipcording is worked using two colors and while learning it is helpful to use strongly contrasting colors so you may recognize mistakes more easily. Measure your threads so that each is about 125% as long as you want to completed cord to be. Cut four lengths, two of each color and wind each piece onto a bobbin and secure the thread, leaving a foot long tail of thread. Tie all the tails together and suspend the threads and bobbins from a point at eye level or higher.
To secure the strings on the bobbins:

Twist the thread just above the length where you want your working
string to end.
The string should make an "X"

Turn the thread over again, so now the stings
cross twice at the "X"

Take the loop that had been over your fingers and slip it over the head of the bobbin.

Pull gently on the part of the string not wound on the bobbin until it
is tight.
While weaving, additional string is let out by rotating the bobbin
while tightly holding the hanging part of the string.
Patterns
You may work your whipcording with threads of all with one color to produce a single color cord (which also hides mistakes nicely) or with four different colors which produces a speckled cord, but when you use two threads each of two colors you can produce either stripes or spirals.
Stripes
Stripes result when you pass the same colors during a stitch - always trading a white for a white and a black for a black. Begin this cord by having the same colors on diagonals from one another.

Step 1 Step 2 Step 3 Step 4 (return to Step 1)
Spirals
Spirals result when you pass
different colors during a stitch � always trading a white for a black and a
black for a white. Begin this cord by having the same colors next to one
another.

Weaving
When first learning the basic principles of whipcording, it can be helpful to practice with a partner for a few minutes. Each partner should control two threads, one with each hand. Be careful not to actually grasp the threads - the bobbins keep the threads from tangling and provide the necessary tension - simply let the threads run over your hands. Then carefully trade threads with your partner - right hand to right hand and left hand to left hand.
Make certain that you always rotate the threads in the same direction (which direction does not matter, consistency does)! If you notice that two strands that have just been passed begin curling around the outside strings instead of each other, stop, undo and redo the last stitch, rotating the threads in the other direction.

The above photo illustrates a bad stitch - the black strings should be
crossing each other, not winding around the white ones. Any time you see this
sort of thing happen - where the strings wrap to the outside instead of forming
a weaving stitch in the middle - undo it and try again.
As you use up thread, carefully release more from the bobbin and adjust the cord's height to a comfortable level. After a few successful passes, you can begin gently swinging the threads at each other, rather than directly passing the threads. Before long, you'll see why this was a popular game with Scandinavian children until recent times!
Weaving by yourself
Once you have mastered the partner method, you may want to move on to the single-weaver method. This method involves one person passing all four threads, but still using the passing on a diagonal that is used in two-person weaving. I find it easiest to place my hands in the weaving so that one string runs over the outside of my thumb and the other runs over my middle, ring, and pinkie fingers. (The stripe pattern is illustrated with the directions, the spiral pattern is below.)

Proper starting position.
The threads should always form a pyramid type shape over your hands (as above). You can change how tightly the cord is woven by moving your hands closer to the weaving point (tighter weave) or further down (looser weave). However, if you push your hands up too far, the tension on the threads is lost and you will produce a lumpy, unsatisfactory cord.

I look worried here, and justifiably so - my weaving strings are
forming a plane, not a pyramid and there is no tension on my forming cord. This
is trouble!

The index finger sticks up between the two strands and helps guide
and separate the strands.
Carefully begin to pass the threads back and forth - each thumb trading a thread with the opposite hand's fingers. Keep the thread running over your fingers - never try to hold it in the palm-side of your fingers as it is very easy to drop from that posture.

Place your index fingers on the strings you want to move - in this case,
the white ones.

Push your hands past each other so that the white strings cross in the
middle at the weaving point and end up on the other side of the diagonal from
where they started. Use the BACK of your thumb and the BACK of your fingers to
hold the threads in their new place. This is the tricky part because you are
essentially dropping the string with one hand at the same time you are scooping
it up with the other. In the above picture, the top hand's fingers will dip
around the string they are currently holding and continue pushing the left
string to its new position AT THE SAME TIME that the lower hand's thumb will
release the left hand string and push the right hand string to its new
position.
This sounds complicated, but stick with me!

Come back to the starting position

Place your index fingers on the strings you want to move - in this
case, the black ones.

Push your hands past each other so that the black strings cross in the
middle at the weaving point and end up on the other side of the diagonal from
where they started.
Use the BACK of your thumb and the BACK of your fingers to hold the
threads in their new place.

Return again to the starting position. Return to the first step and
repeat ad naseum.
Spiral technique illustrated:

Start position

Index fingers guide diagonal strings

Strings are passed across the diagonal - here you can clearly see the outside of the pinky finger scooping the white
thread to its new position.

Index fingers on the opposite diagonals

Trading across the
diagonal. Again note the pinky
and the thumb scooping the threads to their new positions.

And back to the start position. Note that in the Spiral, the colors are now on the opposite hands
from where they started (or they could have moved from thumbs to fingers if
your orientation was offset 90 degrees). This is normal and the strings
will migrate around as the spiral forms.
And - for the especially visually
inclined - a very low-quality video is below!

Since whipcording is such a simple braid, it is difficult to prove for certain that this method
was employed in medieval
