8 shaft diversified plain weave (Strickler #575), using 18/2 natural and 10/2 Green in the warp and 18/2 Green and 10/2 natural in the weft. To me, this is a shadow huck, with both the yarn size and the color contributing to the shadow effect. The threading is a 3-thread huck. I set this at 30 epi, 3 per dent in a 10 dent reed. I didn't sample this first, I just jumped right in--you might try it a little looser for a scarf. It is not real dense, but does not have great drape. At this sett, it might make a good lightweight jacket fabric or placemats.
See the color change progression below:
From left to right, unwashed, washed in hot soapy water, boiled 40 minutes, washed and then soaked in COLD dilute ammonia solution overnight (about a quarter cup ammonia to a gallon of cold tap water). The green cotton has two pigments--yellow and gray. These colors are sensitive to pH; vinegar or any acidic solution will lighten the color and an alkaline solution will darken it. I don't know if both the yellow and the gray respond, or if it's just the gray. My water is neutral--yours may be different, and you will get different variations on this progression. The ammonia dip is my favorite treatment--I do this after washing --no boiling necessary. To my eye, this enhances the gray component, giving it a bluish cast.
