Dreamcloth

Source
Dreamcloth is a type of cloth created by Tailors of at least skill level 500. The pattern is taught by the Tailoring trainers. It is made using eight Bolts of Embersilk Cloth, along with 30 of any type of Volatile (Life, Earth, Air or Water) or 5 Chaos Orbs.

The patterns for making Dreamcloth vary by name according to what type of Volatile is being used, but all make the same type of Dreamcloth.

Only one Dreamcloth can be produced per Volatile type per week, and all are on separate cooldowns. Therefore, it is only possible to make five pieces of Dreamcloth per week without the use of Chaos Orbs.

Patterns and Currency
Dreamcloth is used to purchase patterns from vendors in the Twilight Highlands -- for the Horde or  for the Alliance. Each pattern requires a 525 skill level to learn. ''These are only the patterns involving Dreamcloth. See the vendor pages for a complete list of the patterns they sell.''
