How to Read a Weaving Draft
To understand a weaving draft, imagine that you are floating above your loom looking straight down at it. A weaving draft is the graphic representation of what you would see. There are 4 parts to the weaving draft: the tie-up, the threading, the treadling and the draw down.
The tie up grid is usually located in a corner between the threading and treadling grids. It tells you which treadles get attached to which shafts.
The threading order grid, usually located at the top, is the horizontal grid for your warp. It tells you which colored yarns go in a heddle on which shafts.
The vertical grid is your treadling order. It refers to your weft. It tells you which treadle is pressed and which color yarn is used in the shed created by pressing that treadle.
The draw down is a representation of the woven threads. It gives you an idea of what the design might look like.
I will be including an instructional video in the near future, but for now, I hope these diagrams help you understand a little more than you did before you got here. :) Happy Weaving!
A draft for a table loom will have no boxes filled in at the tie-up grid since there is no tie-up on table looms. You will see multiple boxes filled in on the treadling grid instead.
For up shed vs. down shed (jack loom vs. counterbalance loom), there's now way of telling unless the author states it. If the pattern comes out on the underside of the cloth, then simply reverse the tie-up and it will come out on top.
Thank you, you explain things that a child could understand. I have just acquired an old George Wood dobby loom and was wondering were to start! and I think that learning to read a draft is a good start.
Treadling is read top to bottom, In the photo example you tromp 1,2,3,4,5,6,5,4,3,2 and repeat. This is top to bottom.
Hope that helps.
