In mundane parlance, fabric in dreams is a tactile representation of something we need to know or remember.

A rough fabric might denote a difficulty and a smooth fabric or material a carefully crafted project.

Seeing fabric which has been mended or patched suggests that our original thoughts perhaps had an inherent flaw.

A patch of the same colour may be an attempt to cover this up, whereas one of a different fabric or texture highlights a perhaps innovative solution.
