I can understand not using her images or exactly reproducing her patterns...I had that happen when I had my own business (In custom horse tack) and someone used my images in their advertising. I contacted them and claimed copyright and they took them down right away but they should have known better....
But, if I like her colour choices, I'm supposed to contact her and ask if I can use them? That seems excessive. If I like that she put purple and green together, I'm supposed to ask her for permission to go to my LQS and buy purple and green fabrics for my next quilt? Maybe I'm misunderstanding.
