Sheets and pillowcases used to be made of cotton. That's it. That's all. In winter, they would dry on the line into white cardboard sheets. "Freeze-dried and snow bleached."
Now when I go into Sleep Country, there's everything imaginable. I got the bamboo pillow cases - bamboo is used to make rayon. Very smooth and cooling. And the trend now about smooth, soft and cooling in sheets and pillow cases.
And what's available today? Not just cotton. ,Cotton sateen is available - again very smooth and extra soft. Sateen is different than satin - it is cotton and has more vertical threads than horizontal, so it is more fragile. Satin has very thin, high-thread-count synthetic materials such as nylon, polyester, or acetate.
The smoothest cotton is Egyptian cotton - it has extremely high thread count. Generally a high thread count also means warmer.
What about flax linen - they are said to be soothing and breathable, lightweight and sourced from fields in France and Belgium. Doesn't that sound like a vacation as you sleep?
We live in the time of luxury linens available to everyone. Remember when the Westin Hotel introduced the "Heavenly Bed"? That was just over twenty years ago. It kicked off the luxury bed linen for all trend. Now we're advised on how often we should replace everything in the bedroom - pillows? 1 to 2 years, sheets? 2 years, and so on. Toss, toss. That's part of luxury living.
And today's picture continues the investigation of time. Isn't time elusive and strange? I checked out this article in space.com for a better understanding of time. They let me know it is also illusive. Complicated. I went to work on the floral clock and gave time a few twists.
