Value

Thanks to Holly's suggestion, I went downstairs bright and early this morning. I had woven about two-thirds of a scarf, so I swapped/switched  the 12 dark orange warp ends with the lighter ones for two and a half repeats, (three large squares and two slivers,) and then returned to the dark oranges.   And I think it will look "interesting"; I hope.

This is the view I have as I weave, and picking out the next color combination as I weave is always great fun. (Please excuse the gaping box, the cloth over the warping mill, etc., etc., etc.) What I can't get over is the different appearance of the top two samples. 

These two.  Obviously it is on the same warp, and the blue is the same yarn, so the very different appearance comes from the different values of the fourth, green, wefts.  And these yarns aren't so drastically different, either.  See?

I have a very hard time telling values, so I took three variations of the above photo, moving the lighter ball slightly to the right each time, and then turned them into black-and-whites. 

I think the darker yarns is around 9 on this scale, and the lighter about 5? (I had my money on the lighter being 3!)   To me, the difference in the overall appearance of the cloth seem so much more; the bottom sample looks more complex and richer.

I wove my second piece in that combination.
