I have asked permission twice from designer to use their patterns for humane society and got a Sure that's wonderful from them and a just send me a picture.
I sell belly bands now for dogs and I don't' see how they can say don't sell any from this pattern. Its only two strips of fabric. I figured it out for myself. I did buy a pattern for the girls but found ways it works better and changed it. Haven't sold any of those yet.
No one I know ever wants to pay what the quilts are worth. I even stopped making them for the humane society auction. When I had to bid on one of mine because there was no bids I said that's enough. No more.
