Peter, I was thinking (at the time of my posting this) of frost crystals, but of course, it seems never to get cold enough for good frost crystals where I live, but we do have frost sometime at around 35 degrees if there is enough moisture in the air.
Larry, this is a beautiful shot! I like the composition and the pattern of the feather. Nature is the best designer. You could collect the feather for a pillow! :-)
Thank you Bea. Your suggestion makes me wonder how long it would take me to pick up enough down feathers to stuff a pillow. A long time I imagine. As a young boy, I have memories of sleeping on/in feather mattresses and laying my head on feather down pillows, all made by my grandparents. The winters were cold and there was no heat in the bedrooms.....the days before central heat and air conditioning were affordable to middle class people in the USA. Now it is 'fibre fill' and memory foam!!!
Bea, I have some goose down feather pillows on my sofa, but for sleeping, the fibre fill seems to have a little more rebound to it. I once had a barley husk pillow which was good for a while but eventually the husk began to break down and the resulting powder came through the pillow cover. I'll try anything once!!
