This is a step by step description of how to use Multi-weft Double Weave Drafter to translate a design into a multi-weft double weave draft. It has opened in a separate browser window so that you can try out each step as you read about it.

Here is a four color design that you might want to weave in multi-weft double weave:

The yellow areas will be woven with a yellow warp and yellow weft. The orange areas will be woven with a yellow warp and orange weft. The lilac areas will be woven with a blue warp and lilac weft. The green areas will be woven with alternating blue and yellow warp ends and a green weft.

To draft this design using Multi-weft Double Weave Drafter, you first need to select the number of different warp and weft combinations that will appear on the face of the cloth. Our design has 4 different face warp and weft combinations:

Click Next to go to the next page. There set the odd shaft warp code to B for blue and set the even shaft warp code to Y for yellow. Then fill in the design's warp and weft combinations in any order.

Click Next to go to the next page. Select the number of shafts in your loom and the number of blocks in your design. Set the number of face picks per row to 4 so the final draft will have 20 face picks (5 rows multiplied by 4 face picks per row). Selectt the number of rows in the design. Finally, give the design a name.

Click Assign Weaves to go to a page containing a form for assigning each weave. There enter the warp:weft combination numbers for the face weaves in each row and column of the design.

Click Generate Weft Order Info to have the tool analyze the design and give you the order in which the wefts will be woven in each row of the design. The weft usage information may be helpful for calculating how much weft you need for large designs with varied weft colors.

Click Generate Weft Order Weaves to have the tool give you a table of weave descriptions in which the wefts in each row are represented by their weave order numbers within that row. In our example, each weft color has the same weave order number in each row. In designs using more weft colors, a weft's weave order number may vary from row to row. However, the relative ordering among the wefts always remains the same within each design section.

The wefts that will weave into the back layer of each block are automaticly assigned. The calculations try to have each weft weave into the back layer immediately to the left or right of its face area. Where that's not possible, two different wefts weave into the back of the same block using pick and pick to ensure that they both weave into the back layer.

Click Generate WIF to have the tool generate WIF information for the draft that can be read by weave programs. To use the WIF draft in a weave program, you will need to first save the WIF information as a text file.

Once you have a WIF file, you can look at your draft in a weave program. At first glance, the draft doesn't resemble our intended design very much. However, it does contain all the information needed to weave the design guided by the row weft weave order assignments.

The weft colors in the draft correspond to the weft weave orders in their row as follows:

Draft Weft Color Weft Weave Order
pink 1
green 2
orange 3
blue 4

    Note: ArahWeave PE automatically modified the generated draft to use only 15 shafts

If you want to see the design before it appears as the cloth woven, you may want to change the threading and the warp and weft colors to match those you'll actually use to weave the design. For our design, changing just the threading doesn't result in a draft that looks much like the intended design.

Changing both the threading and yarn colors results in a draft that reveals more of the intended design.
