I was looking at some 18/2 Merino sitting on my shelf and thought that it might be a good idea to do some Deflected Doubleweave. So I re-read the article "Deﬂected Doubleweave: beyond the basics" by Madelyn van der Hoogt. I tried various profiles as suggested and then played with my weaving software (Pixeloom) to see if I could automate the creation of the full threading. I ended up with this method;
1. Draw a twill threading with alternate colors in the warp. This example is very simple just to illustrate the method.
2. Expand the threading by 2.
3 Use Block Substitution selecting"overshot".
4 Change number of treadles to 8.
4 Change the tie up to a deflected double weave tie up. I have started keeping all my tie-ups, threadings, treadlings and colour schemes in a Library folder and then using the Import function to bring them into whichever draft I am working on.
5. Use "Tromp as Writ" function to redraw the treadling
6. Use "Use warp colours" function to make weft colours the same as the warp
I did this exercise starting with a various 10 shaft twills so I ended up with several 20 shaft deflected double weave drafts. I came across a draft for 16 shaft deflected double weave in the Files section of WeaveTech (DeflectedDoubleWeave.WIF posted by R S Blau) which helped me understand the tie up variations that are possible. It was this draft that lead me to the "Ultimate" threading that I have referred to in previous blogs
