Any flat woven cloth can be translated into a double cloth with a fold on either the left or right by using this utility on the design menu:
Create Double Cloth Icon
First design your cloth as if it were going to be woven without the fold (e.g. woven flat) at full width. Be sure to save your draft before clicking create double cloth as this action will transform your draft. It's good practice to save the full width draft with a name different than the double cloth version so that changes, if needed, can be easily made and the double draft regenerated.
For example, the simple twill pattern below, requiring 4 shafts and 4 treadles has a total of 800 warp ends, sett at 20 epi and requires 40 inches in the reed. Woven double, the draft will require 20 inches in the reed and 8 shafts and treadles.

Options for Create Double CLoth
After clicking the Create Double Cloth icon on the design tab, the above options are shown. Choosing fold on left and clicking ok transforms the draft into the following that will weave with a fold on the left and sett at 40 epi, requires double the shafts and treadles.

The generated draft weaves the bottom layer with shafts 5-8 and assumes a treadling sequence of TBBT.
The project information cloth construction settings now move from Normal cloth to the following:

NOTE - if your cloth, prior to creating the folded double cloth, requires two shuttles, the shuttle sequence needs to be altered. We are working on an option for a future release that will ask if you plan to weave with 2-shuttles so that the treadling will work correctly.
HINTS ON MANAGING YOUR DOUBLE FOLDED PROJECTS:
As mentioned earlier, always design and save a file with your Project designed "Flat", as if you were weaving with the full width.
Always plan for an even number of Warp Ends.
Use the Project Settings Dimensions to view the predicted final size that are calculated based using your Calculation drivers using the Flat version of your design. Also, calculate yarn requirements on the project settings using Flat version of your design.
Be certain to always save any changes to the Flat version before clicking "Create Double Cloth". Once you do "Create Double Cloth", immediately do a "SAVE-AS" to save it as a name you recognize as being folded. Often it's helpful to go back and make changes to the flat version, then redo the "Create Double Cloth".
When designing with stripes, check the Warp Winding Plan on the Folded Version of your design; depending on where you placed the color changes in the flat version, when folding it could create a lot of color changes for your warp chain. Sometimes a simple, small change in the width of a stripe can eliminate many of the color changes that result when winding for the folded project.
