I wasn’t aware of this (because I don’t go looking for them): the KnitPicks call for designers (a PDF). Design something original for exclusive KnitPicks use for a year, compensation from $50 to $400, not clear what happens to the copyright, but the terms seem to suggest it’s retained by the author, since additional payments may be negotiated if the pattern is to be distributed by another method after a year of KnitPicks exclusivity.
The term that caught me:
You will provide an affidavit that the pattern has been tested, signed by your tester.
Unless there’s some other definition of “affidavit” I’m not aware of, they’re asking for a statement under oath from a test knitter that the pattern was tested? Why? So they can institute a third-party claim when some deranged knitter sues them for errata that causes him/her to destroy a $20 investment in yarn?
Do they pay for the notary public’s fee for taking the oath?
(Yes, I’m guessing that they don’t actually mean a real affidavit, since they don’t ask for as much from the designer in certifying that the design was original — I think.)
