People often ask if they can sell things made from my patterns. I always say yes!
You can do whatever you want with things made from my patterns. You can’t sell the pattern itself without permission! But you can absolutely sell the things you’ve made from the pattern.
As far as I can tell, there’s not a way for a designer to prevent a knitter from selling what they make (unless explicitly agreed to before purchase). So while I don’t mind at all, I don’t actually think I could stop you, even if I wanted to.
This is a bit controversial! Some designers say things like ‘for personal use only’ (a few are rather insistent about it). And I am very much not a lawyer, but I’m pretty sure that’s not how it works. Or, at the very least, designers would need to get buyers to explicitly agree to that restriction before they bought the pattern in order for it to be enforceable (just having that language in a pattern where you don’t see it before you buy it isn’t enough).
I’ve linked an article from the Craft Industry Alliance with more information. But the gist is that copyright protects the pattern, not the things people make from the pattern. To protect the things people make from a pattern, you’d need a licensing agreement. And a designer would need to get the person buying the pattern to explicitly accept that licensing agreement before the purchase for it to count.
So while some folks may prefer you not sell things made from their patterns (and it’s certainly gracious to respect that), I’m not sure it’s enforceable (again, not a lawyer).
Frankly, I’m not sure why designers mind. People who buy finished objects and people who buy patterns aren’t the same folks! It’s not like someone buying the finished object would have bought the pattern instead were the finished object not available.
So, as far as my patterns go? It’s totally fine with me if you want to sell what you make. In fact, I’m flattered!
As far as other designers go? If it’s important to someone that you don’t sell things you make with their patterns, it’s kind to respect their wishes. But as far as I can tell, that’s not a limitation anyone can enforce.
