Thanks for the link, Jan--it's very helpful! I thought something like that had been posted before but after doing a search, I couldn't find it in any previous posts.
I COMPLETELY agree that a designer should be upset if someone were trying to pass off their design as their own (I would be!), but only if the crafter is claiming the design as their own. As tokmom said, her friend doesn't claim the design of the girls' skirts as her own design, just that she handcrafted them, which she did. I would not and have never claimed a design as my own, but the time, work, and money used for materials that go into making is certainly is mine. If I make something for a family member or myself and a someone comments on the design, I always point them in the direction of the pattern. If it's simply a matter of putting a disclaimer on FO's you intend to sell like a label or a sign at a craft table that says, "Handcrafted using a design by Jane Doe", that would certainly be easy enough to do. I am not trying to take anything away from designers, because frankly, I could do NO crafting whatsoever without a pattern. I know it takes time, skill, hard work, and extreme talent to design patterns; I have neither the talent nor skill to design patterns myself, which is why I need to use others' patterns. So their hard work is invaluable to me and completely appreciated...without it, I couldn't knit, sew, or crochet. I'm certainly not trying to demean what they do, because if it wasn't for them, I wouldn't create anything.
If I'm a designer--no matter whether it's sewing, knitting, etc.--I have two choices. I can either design a pattern and sell it and make a profit that way, or I can choose to not make the pattern available to anyone but I can mass produce my design into FO's and sell them that way. If a designer chooses not to mass produce their design for whatever reason and opts to only sell the pattern, I still don't understand why there's opposition to the pattern purchaser making a profit.
Ensuring a designer gets credit for FO made from their designs is very easily remedied by the seller including a label in FO's or putting a sign up at your selling table indicating that it's a design by such-and-such a designer. Maybe designers could make a stipulation like that in their patterns if they are concerned they won't get credit for their designs, instead of strictly forbidding any type of duplication for profit at all?
