{{Main|Thai silk}}
Silk is produced year-round in Thailand by two types of silkworms, the cultured Bombycidae and wild Saturniidae. Most production is after the rice harvest in the southern and northeastern parts of the country. Women traditionally weave silk on hand looms and pass the skill on to their daughters, as weaving is considered to be a sign of maturity and eligibility for marriage. Thai silk textiles often use complicated patterns in various colours and styles. Most regions of Thailand have their own typical silks. A single thread [[fiber|filament]] is too thin to use on its own so women combine many threads to produce a thicker, usable fiber. They do this by hand-reeling the threads onto a wooden spindle to produce a uniform strand of raw silk. The process takes around 40 hours to produce a half kilogram of silk. Many local operations use a reeling machine for this task, but some silk threads are still hand-reeled. The difference is that hand-reeled threads produce three grades of silk: two fine grades that are ideal for lightweight fabrics, and a thick grade for heavier material.

The silk fabric is soaked in extremely cold water and bleached before dyeing to remove the natural yellow coloring of Thai silk yarn. To do this, skeins of silk thread are immersed in large tubs of [[hydrogen peroxide]]. Once washed and dried, the silk is woven on a traditional hand-operated loom.<ref>[http://www.bangkok-thailand.com/about-thai-silk.htm About Thai silk] {{webarchive|url=https://web.archive.org/web/20070509190809/http://www.bangkok-thailand.com/about-thai-silk.htm |date=9 May 2007}} from World of Thai Silk (commercial)</ref>
