One of the main factors that determines the quality of a sheet is the cotton used to construct it. On their website Sferra explains that, "Egyptian cotton is the finest cotton because it is one of the longest staple cottons in the world, the staple being the indivuidual cotton fiber. The longer the fiber, the better it can be spun into smoother and stronger yarn." You can find sheets anywhere that will boast a 1000 thread count, yet they may feel rough because the quailty of the cotton or the finishing process was poor.
Sferra, one of our top sheeting lines, recently launched a campaign called "Lose Count" which explains different types of sheeting, what to look for in a quality sheet, and what sheet coule be right for you. Friend them on Facebook to learn more about what makes a great sheet!
So friends, the moral of the story is...you can't judge a sheet by it's thread count.
