I’d answer no to each of those questions and then waffle and say it depends on what kind of contracts are in place. And the amount of greed involved.
I’m sure lots of fabric designers have been watching this whole Kate Spain fiasco and having serious thoughts about what it could mean if quilters just say enough is enough and quit buying fabric by designers who create such a stink about copyright. Contracts with manufacturers might be a little hard to come by for those designers.
