Shopping for silk, some basic types of it should be known. The main two types are listed below.
There are two basic types of silk, wild silk and cultivated silk. Wild silk, as you might expect, comes from wild silkworms. The filament threads from them are not long continuous threads like those from cultivated silk so it is not as durable or as strong as cultivated. For sheets, durability is a big consideration. Although they cost more, sheets made from cultivated silk are recommended because the thread strands are much longer. Cultivated silk bedding is most often referred to as Mulberry Silk bedding because that is the only food cultivated silkworms eat. Mulberry silk is the most expensive. Tussah, Habutai, and wild silk can all be quite nice too and are a little less expensive.
