Actually I haven’t felt that the days are getting longer, although, since I live in the northern hemisphere, I know that the days do actually get a little bit longer each day as we pass the Winter solstice. However, for our friends in the summer hemisphere, as our days are getting longer, their days are getting shorter, which comes as no big surprise. So, as I mentioned earlier, the OP needed to qualify his query for it to make worldwide sense.
Thanks for picturing the color samples. I love colors. One of the gifts that I gave my wife for Christmas was a rather large box containing 200 x 300 meter spools of quilting thread, all different colors. So you name the color, and we have something close to it.
My wife gave me a used English-woven sport jacket that I actually purchased on ebay. On close inspection I see that there are a couple of minor places where the wool threads are broken (probably eaten by moths). So I will need some wool thread of the precise color to do the repair weaving, this from an ample supply of colored yarn. I will also need to lose a few pounds if I hope to comfortably button the jacket.
By the way, I’m glad that the days are getting longer. I feel like we are over the hump, and it’s all downhill from here.
