From the second article:
"If you make pictures of the finished quilt, then I think there is likely to be a problem..." That depends upon the purpose of the pictures. If you have made the quilt from a lawfully acquired pattern, that pattern purchase gives you the rights to the item made from that pattern. Your quilt; your pictures of your quilt. If you want to sell the quilt, copyright law specifically gives you permission to use pictures to sell it.
"Finally, don't make money off anyone else's work" Why not? If you purchased the pattern you have that right. They voluntarily sold it to you. NASCAR drivers don't build their own cars; they buy Fords and Pontiacs and modify them. They have that right. Don't you think Ford dislikes when the race is won by a Pontiac? But imagine Ford saying "This car can only be used for non-commercial home use". Profit is a perfectly reasonable motive and is recognized under the law.
In a follow-up post she says, "Again, it's not the creation of the potholders that matters, it's trying to sell them." Wrong, wrong, wrong. It is perfectly legal to do so and we have established that fact in lawsuits against Disney, Major League Baseball, Sanrio, and United Media (Peanuts). There is absolutely no court case that says otherwise
Me again... that goes for the pattern and any copywritted fabric that is used in the pattern. I just can't start printing copies of the pattern or make the fabric and sell it.
