What's what and who's who

There has been a lot of discussion of late, in the knitting circles I frequent, regarding the term "designer". Who is allowed to use that title? When? How? What hoops must they jump through? May they call themselves a designer if they do half the work or must they do it all? May they call themselves a designer if they have only created one design or must they create a design collection? May they call themselves a designer if they only design dishcloths or scarves or hats and don't sell patterns? May they call themselves a designer if they make minor changes to a store bought pattern? Who can answer these questions? Can they speak for everyone?

...oh, you thought I would answer any or all of these questions? ...sorry.

Take care,
Leanne

PS If you do have the answers please share. Thank you.
