"A wattle cloud rising at three strides by quarter sight, obscurity grade high, for instance, must always be stressed with the third finder and an oblique nod, like so."

Cloudcraft was a technique used by cloudwatchers to describe various cloud formations. It was a complex, difficult code involving finger movements and body language. This was taught to students at the Fountain House school of Sanctaphrax, and the pupils learnt cloudcraft by repeating the tablesin the Great Tome of Skylore until they could recite them off by heart.
