In some
religious community, perhaps the
Shakers, it was believed that
only God could create something perfect. Hence creating a
perfect object was considered
trespassing in God's domain. So all crafts, from
chairmaking to
quilting to
painting, had to include a
perfect flaw. Of course, some
flaws rendered the object unusable. So a secondary art form emerged, of creating a beautiful
"flaw" inconsistent with the overall work, yet
appealing in its own right.
example: The sweater I knit with one cable twisting in the opposite direction from the other cables.
