If that article is really correct, then I think the laws need to be changed. I do think it's ridiculous, that someone should have to request permission to share a photo of a quilt they've made from a pattern they've purchased. I think the crux of the matter, where quilting is concerned, is that very little is original. This woman's Magic Tiles quilt (I've not seen it) is probably not original. From whom did she get permission to produce and sell the pattern? With whom did she share her profits?
I believe, once a pattern is sold, that should be the end of it, as far as end product is concerned. The designer has received her monetary due; there should be no further claim on the purchaser who uses the pattern to make a quilt for personal use -- whether to give, or to sell, or to display. If a designer wants to keep such control over her design, then don't produce a pattern and sell it! She is trying to have it both ways. She wants to profit from her design by making it available for purchase, and she also wants to keep exclusive control over it. It's just absurd when you consider the implications in practical terms. Hopefully copyright law will evolve so that it makes more practical sense.
