With weaving, when in doubt, keeping it simple is the most elegant solution for me. So with Julie's Shadow Weave scarf, I decided to use the two dark grays in DLDL in the warp and the weft. But I sense there are further color options. (I'm not too confident if these screen shots will show well, but here goes. Clicking and looking at the larger picture may help.)
In this post, D stands for the dark(er) color, and L for the light(er) color.
First, the simple black and white. Both warps are in LDLD, but in the left, the weft is also in LDLD, while in the right, it is in DLDL. They look quite different here. My understanding of Shadow Weave is the left version. The draft on the right seems more "corrupt" in this photo than in a real draft; try clicking on the photo to see they are not as dissimilar.
(EDIT: Peg says they are both Shadow Weave, so I should say I like the one on the left better.)
(OK, a question. On Page 77 of the 8-shaft book, the warp is in LDLD from right, but the weft is in DLDL from the top, and still the cloth looks more like the left one. What am I missing?)
With that in mind, say you have yarns in the same hue but values A, B, C and D, with A being the lightest and D being the darkest.
I could make a warp with ABAB, and weave with CDCD in the weft as in above left, or DCDC as in above right.
Or, I could make a warp with ADAD, and weave with BCBC in the weft as in above left, or CBCB as in above right.
Of the four above, I like the bottom left ADAD-BCBC the best. With undulation, theoretically I could introduce two (or more) pairs both warp- and weft-wise where the threading angle (for want of a better word) changes, to create an illusion of depth in the cloth, but this sounds more like the realm of mathematical possibilities for me at this point.
The more urgent problem with this particular warp is the characteristics of my particular cashmere, which feels nicest in something like a loose 2/2 twill at around 15DPI. Shadow Weave, though it looks otherwise, is basically plain weave, so I'm very worried about the way this cashmere is going to feel, based on the sampling I did yonks ago. But Julie won't be comparing her scarf with a 2/2 twill piece, so I may be worrying needlessly; like a nice cashmere coat, it will feel luxurious and light compared to other fiber, and will probably age better than the looser twill.
I just need to sample vigilantly tomorrow, and if need be, resley.
