How to read a rigid heddle weaving draft

Most of the time when you are weaving on a rigid heddle loom and following instructions, there will be written notes for how to weave a pattern.

For example, in any of my rigid heddle classes you will see threading instructions, telling you which holes and slots to thread, including colour order wherever it’s applicable. You will see any extra instructions for using pick up sticks if they are being used. All these things will be shown and often written in a file with step by step text instructions.

But, what about weaving drafts? Weaving drafts are not something that a rigid heddle weaver needs to know, because, as I mentioned above, most weaving patterns or classes for rigid heddle will have written instructions and won’t even mention a weaving draft.

However, learning to read a basic weaving draft can be really useful for two main reasons:

1. It helps you to gain an understanding of how your rigid heddle loom actually operates. You will discover this in a moment as we go through how to read a plain weave draft and how it translates to your RH loom.

2. Many rigid heddle weavers choose to venture into multi shaft weaving – either by adapting their rigid heddle loom or by purchasing a table or floor loom. Knowing how to read a draft is invaluable to the weaver who aims to weave with more than two shafts at some stage.

Today, we’re going to look at a simple plain weave, two shaft weaving draft. I chose to help you learn about a two shaft draft because I want you to focus first on learning the basic layout of a non complicated weaving draft, and also because a rigid heddle loom is a two shaft loom.

You can see that I opted for bright and contrasting colours so that you can distinctly see the pattern. Personally, I would probably not choose these colours for a project, but some of you may love them! 😬

This is the most typical layout for a weaving draft, but if it is an older draft you are looking at, the information may be in different places, for example, the line of numbers I have at the top may be at the bottom instead.

Alright, let’s get into the nitty gritty by learning the different parts of the draft and what they mean, starting at the top.

Save

The top section circled in red is the threading. For plain weave on a rigid heddle loom we use two shafts and these are represented by the numbers 1 and 2 that repeat across. The threading section is a horizontal bar on the draft, but indicates the vertical purple warp threads. You can think of these numbers as being like the vertical threads of your warp.

You can think of the holes on your heddle as shaft 1 (number 1 in the threading section) and the slots on your heddle as shaft 2 (number 2 in the threading section).

Save

To find the start of the threading section, we read from right to left, beginning in the first box in the right hand corner, which is a number 1.

Also note the colour that appears above the number 1, which in this case is purple.

This tells me that my first thread for my warp is a purple thread that will be threaded in a hole. The second will be in a slot. Then a hole, then a slot, and so on.

Save

This would be an easy warp as there are no warp colour changes.

Next I want to discuss the tie up box.

Save

When using a multi shaft loom, you need to know which shafts need to be tied up to which treadles, this is where the tie up box in the top right corner of the draft comes in.

The circles you can see in the box match up with either number one or two on the threading section, indicating which shafts are to be used. The circle usually means that the tie up is for a rising shed loom. An “X” will often mean the tie up is for a sinking shed loom.

How is this relevant to the rigid heddle weaver, considering we don’t have to tie up treadles?

It simply shows us which shafts need to be engaged in order to weave the pattern. If we thread our shaft 1 in the heddle holes and shaft 2 in the heddle slots, as described earlier, we don’t need to do anything else (like tie up treadles) in order to start weaving those shafts. The warping and threading of the heddle is all the preparation we need.

Save

The long, vertical box to the right of the draft is the treadling section. The box is vertical, but indicates the horizontal part of your weaving, which is the weft. My weft is yellow, and this is indicated by the yellow box next to each number.

Again, as rigid heddle weavers, we don’t “treadle” but we do manipulate our heddle in order to open shafts, and this box gives us the correct order we need to use to weave the pattern.

On the rigid heddle, we operate the heddle for plain weave by either lifting it into the up position or placing it in the down position.

When you lift your heddle up, have a look at what is happening with the threads. All the hole threads are lifted up, and the slot threads stay down. The space in between the two layers of threads is our shed.

Now, when you place your heddle down, the opposite occurs – all the slot threads pop up and the hole threads stay down. This creates a second, different shed. In that case:

Heddle up = Shaft 1 engaged

Heddle down = Shaft 2 engaged

So, we understand that the heddle just goes up and down and that makes our 2 shafts. But let’s look more closely at the draft to ensure that we can visually follow the changing of shafts.

Save

We start reading the treadling (or order of shafts) in the first box that appears under the tie up box. The treadling sequence will not always be indicated by numbers, there may be a filled box, a diagonal slash or similar.

Also, some drafts will use numbers to indicate how many times you are going to weave a certain pick. But, because we are just alternating between shafts 1 and 2, I have used the numbers 1 and 2 underneath the circles.

For this draft, the first number is on the left, underneath the circle that indicates shaft 1. For the RH weaver, shaft 1 means hole threads, which means heddle up.

Save

When you have woven your shaft 1 pick you will then change to the next shed by following along to the next number in the next line down. It is a number 2 and so for the RH weaver, that means the down shed.

After weaving this shed, you then follow to the next row down, which is a shaft 1. And so on.

The last part of the weaving draft is the drawdown.

Save

The drawdown is essentially a diagram of the fabric you will weave. It provides you with a visual representation of what your pattern might look like.

Naturally, elements such as your sett and chosen yarns can vary the look of the cloth greatly, so your finished piece will not necessarily look just like the drawdown. It shows the interlacement of your thread colours.

With our plain weave, checkerboard pattern you can easily see that the alternating colours in each row of purple, yellow, purple, yellow represent our warp and weft colours, and also our shafts one and two.
