After checking the momme weight, another element should be put forward is whether it is made with mulberry silk. As we all know, mulberry silk is indeed the silk bedding king of all.
Look for bedding made with mulberry silk (also called cultivated silk or bombyx silk). Avoid Habotai silk. It has a rougher matte finish and is made from wild silk which is of a lower quality than cultivated silk. Wild silk strands are not extremely long like cultivated silk strands are so they need to be spun together to create length creating a silk that is not as durable as the long single thread filaments harvested from cultivated silkworms.
So the next time you go shopping for silk bedding, don’t consider the silk sheets with seam is of lower quality, and it may not the best to reflect the class. Instead, the type of silk used, the momme weight should be the best indicators that will tell how high or how low the quality of the sheets are.
