Question about the description of a part

[Manfred Schaefer]

Because the heads are reversible. The torsos are not.

What's wrong with labeling all parts with patterns on, for example, the front and back with the addition of “2-Sided Pattern”?
It would provide an additional filter or search element and, to my knowledge, does not contradict any rules.
This could possibly become a new rule and create more clarity.
