Final answer:
While the question is about when and how the fleece cap should be worn, the information provided only explains the 'warp-wrapping' weaving technique used to create the design of the cap.
Step-by-step explanation:
The fleece cap should be worn in contexts that align with its design and purpose, which may be cultural or pragmatic. The method of creating the central cloth's design involves a technique called 'warp-wrapping', where colored fleece is wound around sections of cotton warp threads before the weaving process.
This creates a pattern with 32 geometric faces, which could inform its use in cultural ceremonies or traditional dress.
However, no specific information on 'when and how' the fleece cap should be worn is provided, so it's important to consider the tradition or guidelines of the particular culture or group that uses this cap.
