Beginning Tablet Weaving
by Eve the Just
List of Tools
Beater (eg. tapered edge of a shuttle or a wooden ruler)
Something to secure the ends of the weaving to (eg. board and clamps, chair and belt, loom)
Optional(but really nice to have)
Wide toothed plastic combs
twist ties, kilt pins or knitting stitch holders (look like big kilt pins but not sharpened), of the three the stitch holders are the best
Basic Weaving Concepts
Warp - the threads which run in a vertical direction. These threads represent the framework upon which you work your weaving.
Weft - the thread(s) which run(s) in a horizontal direction, most commonly a single thread, but can be multiples. The warp passes back and forth and fixes in place whatever manipulations you make with the warp.
Twining: S and Z
Memory trick: Santi ClauZe
Twining refers to the direction the cord is twisting in either spinning or weaving.
Look down a cord or one card's worth of weaving and watch the rotation of the fibers. An anticlockwise rotation is referred to as S twining. A clockwise rotation is Z twining. From on top, if you see this angle: / it is Z twining, if you see this angle: \ it is S twining. Note that the angle matches that of the "vertical" part of the letter.
The threads in a single card must be either ALL S or ALL Z. You CANNOT have both sorts of threading on one card. If you do, it will not turn. The threading looks like this from a top view:
When S threaded cards are turned forward they produce a Z twined cord, when turned in reverse, they produce an S twined cord. The opposite is true for Z threaded cards.
A Shed is a term for the space between two layers of warp threads through which your shuttle and thus your weft thread will pass.
A shuttle is simply something around which you can wind your weft threads, usually long and skinny with notched ends and made of wood or plastic. It is not necessary to start weaving but is a nice tool to have and not terribly expensive.
Tablet Weaving Patterns
Basic patterns in tablet weaving are achieved in one of two ways; threaded in patterns and woven in patterns.
Threaded in Patterns are the simpler of the two in terms of weaving. The pattern visible in the final product is derived completely from what colour is threaded in each hole of the cards and in what direction the whole card is threaded. Weaving consists of simply turning the cards as a pack or as a set of packs. The final pattern can be figured out using the threading pattern and minimal instructions.
Many simple patterns can be made by this method including diamonds, triangles, lattices, chevrons and stripes. Because of the nature of tablet weaving, it is well suited to designs with 45° angles. In order for the line to be smooth, the angle of the twining must match the angle of the diagonal, thus this angle: / must be made up of threads twining in a Z direction (S threaded cards turned forward or Z threaded cards turned backward) to be smooth. Vertical lines are also possible. Horizontal lines on the other hand will tend to look "toothy".
There is apparently very little evidence for the use of these kinds of patterns in period.
Woven in Patterns are more complex to weave as the initial set up of the threads does not completely determine the final product. In some cases, the final product will not resemble the threading pattern in the least.
This effect is most easily illustrated with double faced weaving. In double faced weaving you can produce any two-coloured design that you can produce on graph paper with squares one unit wide (horizontal/weft direction) by two units long(vertical/warp direction).
The Ram's Horn and Spirals are other examples of woven in patterns. To achieve these you have to "flip" cards. A flip is done so that the front of the card switches and becomes the back of the card. The result is that the direction of the threading will change (from S to Z or from Z to S). Reversing the turning direction of the card MAY produce the same result depending on the order of the colours threaded on a card.
The cards used in tablet weaving can have any number of holes. Four holes, one in each corner of a square card is most common but 3, 5 and 6 holed cards can also be used. Four holed cards with only 2 holes threaded can be used to replicate simple weaving as there are only two possible sheds.
Cards can be made of wood, bone, antler or cardboard. The easiest/cheapest way to make cards in modern times is using cereal boxes. The most inexpensive of the more durable materials is a sort of counter-top laminate you can get at home depot type places for about $2 for an enormous sheet - cutting the cards then would require power tools and sanding though.
I like my four holed cards to be 6cm square with a hole punched about 1/2" in from the edges on each corner (yes, I know, pick a measuring system and stick with it). The corners should be somewhat rounded and it is best if the holes are round and smooth as well, as this is easier on the yarn.
For the purpose of explaining patterns, the four holes are often assigned letters. Viewed from the right, the common assignment is:
The first step in setting up tablet weaving is deciding the length of your warp. Decide the length of your intended final project, add 20% for take-up (length lost by twining), then add 50cm to make room for the cards. The final equation is:
warp length = 1.2 x final length + 50 cm
Select your yarn carefully. I recommend crochet cotton as a good, easy to find, easy to weave starter material which is available in a fairly wide selection of colours. You need a yarn that is fairly strong (the warp is under a lot of pressure and you don't want it to break) and it is also nice to have a yarn that is fairly smooth. Fuzzy yarns get "eaten" by the cards and will result in a lot of fuzz in your carpets under your weaving. I also recommend sticking to yarns that are natural. Yes, they might cost a little more, but the main expense in tablet weaving is the time you invest. Working with a lesser material will result in a MUCH lesser product. Our ancestors certainly didn't have acrylic so I don't see any reason why we should use it. It can also be argued that our ancestors didn't have cotton, maybe true, but at least cotton is natural. The most period materials would be wool and silk with silk being seen most often. Linen may have also been used but I have not seen evidence of its use. Embroidery floss can also be used and is the most likely modern source for silk yarns. I believe that this is a more expensive source for materials than crochet cotton, but the colour selection is extremely vast and there are online sources which list colours that correspond to dyes available in period.
For your first piece of weaving I recommend using 16 cards threaded with one colour in holes A & B and a second colour in holes C & D. Try to select two high contrast colours. Think heraldry; a metal and a colour works best. This will allow you to get a good look at the different patterns which can be achieved. Go to the end of the article to read the turning pattern I make people do in an in-person tutorial.
Once all your cards have been threaded, be sure to fix them in place with a twist tie, kilt pin or knitting stitch holder run through one of the holes of each card, the same hole for each card (eg all through hole A). You want to do this so when you pick up the warp all the cards don't fall into a jumbled mess. I usually run my twist tie through the top hole closest to me. This consistency helps me to keep the pack together and to remember what position the cards were in when I stopped.
Tie the threads together on the side of the cards closest to you. This should be the short end of your warp. Affix this end to something stable and comb out your warp threads using either your fingers or a wide toothed comb. If you're going to use a comb, buy one SPECIFICALLY for this purpose - hair products in weaving BAD and these combs usually only cost $1-3 anyway. Don't be a perfectionist when combing, all the threads will NEVER lie perfectly. Just be gentle and get it looking decent. If your warp is particularly long, you may wish to use warp chaining to prevent tangling.
The final bit of set up is to untie the short end, affix the long end of the warp to a stationary object and affix the short end to either a second stationary object or to yourself (most commonly to a very sturdy belt). When affixing the short end to yourself, this is called "weaver tensioned" as your position will determine the tension of the project. Personally, I suck at this and much prefer using either a loom or a set of C-clamps and a board.
The basic motion of weaving is a simple repetition of 4
1. Turn the cards one quarter turn
2. beat the weft down
3. pull the weft to pick up the excess "tail"
4. run the shuttle through the new shed, leaving a "tail" behind.
In the first step, the direction you turn the cards will depend on the pattern you are weaving. If you have to manipulate any cards, that is step #0 in the order.
In step 2, try to make your beating consistent, you will find that to maintain consistency, you will have to beat harder when the project is under more tension to achieve the same result. Properly maintaining the tension makes this much easier. Weaver tensioning allows for finer control of tension when done properly.
In step 3 you have to practice consistency again. Using a ruler as a beater will help as you can use it to check the width of your band and maintain it. Don't pull so tight that the threads get shoved on top of each other. Also don't leave it so loose that you get a fringe - unless of course you want that effect. However, in order to make a proper fringe, you need two different weft threads; one to hold the fabric together as a band and the other to make the fringe.
Dealing With Twist
You will find that if you constantly turn the cards in one direction that a twist will build-up in the warp on the other side of the cards. There are a few ways to relieve this twist build-up.
The easiest is to work a reversal into your pattern. The simplest example is the four forward, four backward pattern. At the end of this series there will be no twist build up. The basic theory is that you must go an equal number of turns forward and backward, no matter how many that is or which comes first. This way they will cancel each other out.
Another method of dealing with twist build-up is to use a weight tensioned loom set-up. In this set up, the warp threads are fixed to a stationary object at the short end, run through a comb and each card's worth of threads is attached to a weight at the far end (think fishing weight). All the weights must be equal. This set up is excellent for providing even tension and for dealing with twist build up as the weights can simply rotate as they hang. It does however require a space in which to set up which you will not have to disassemble before the work is complete. It also requires a bit more materials (fishing weights). It also to my knowledge puts a limit on the length of warp you can use (the length of your set up and dangle space).
Another method is to use two upright poles to set up the project and use a continuous warp. This loom set up is very often illustrated in period. In order for this set up to work, you must thread the cards as a pack and run the threads around the poles dropping off one card each time you reach the "middle" from either side. You must also drop off your cards alternating S and Z threading. Or rather, if you drop a card on the right side first, then the card you drop on the left side must be threaded opposite to the card you dropped on the right side. Thus, when you weave, the twist from the S threaded card will be able to make its way around the far pole and cancel itself against the twist build up from the Z threaded card on the other side.

A Beginning Weaver's Tutorial
Go through these in order and do them all on a single piece of weaving. Think of it as a "sampler".
Start with all your cards threaded as mentioned above (A&B one colour, C&D another in high contrast) with all cards either S or Z threaded (pick one and make them all the same). Now, start turning forward. You should be getting toothy horizontal stripes, each one made up of two bands of the colour. After a bunch of turns you'll notice a lot of twist building up. Reverse your turning direction. Notice that if you reverse it after 2 bands of the same colour (at the end of a stripe) you will get an extra wide band. If you reverse it after only one band of a colour (in the middle of a stripe), the reversal stripe will be the same width as all the other stripes. Also notice that at the reversal the surface thread is in straight vertical rather than twisted (neither S nor Z twined).
Do not do step 4 of the regular weaving sequence before you start manipulating the cards. Start at one edge of your pack of cards. Leave the first card as is, this is the first card in the sequence. Turn the second card 1/4 turn forward. Turn the third card 1/2 turn forward. Turn the 4th card 1/4 turn backwards. Start the sequence again at one. Repeat until you reach the end of the pack of cards. Now do step 4 of the normal weaving process (run the weft through the shed and leave a tail). Turn all the cards forward. Keep weaving as normal. You're going to have either a really nice smooth diagonal line or a toothy diagonal line. It's a 50/50 chance and not really important which one you get because if you turn it over, you will see the opposite possibility on the bottom side! If you keep going and do a few reversals you'll have a nice "indented" pattern on the smooth side.
Chevrons and Diamonds
Do not do step 4 of the regular weaving sequence before you start manipulating the cards. Divide your pack of cards at the center of your cards. One half will be your template. You want to make the other half a mirror image of the template. For example, if the template half is all Z threaded, the mirror half will be all S threaded (make this change first). Now, work your way out from the center making all the colours in the mirror half line up with those in the template half. I can't think of a good way to explain this, if you can't follow it, write me (evethejust at gmail.com). Now do step 4 of the normal weaving process (run the weft through the shed and leave a tail). Turn all the cards forward. Keep weaving as normal. You should be getting nice chevrons on one side of your weaving (top or bottom). To get diamonds simply make a reversal. Where and how often you make your reversals will determine how your diamond looks, what colour is in the centre etc. There is a lot of variation possible, experiment a lot, remember, this is just a sampler, so try a lot of things to find something you like.
Double Chevrons and Diamonds
Do not do step 4 of the regular weaving sequence before you start manipulating the cards. Divide your pack of cards in quarters (if you did 16 cards like I suggested this will be easy). Make the outside quarter of each half mirror the inside quarter just like you did when making the regular chevrons/diamonds. Now do step 4 of the normal weaving process (run the weft through the shed and leave a tail). Turn all the cards forward. Keep weaving as normal. You should have nice double chevrons and with reversals, double diamonds. As before, experiment and have fun.
