Hi. Sounds great to me! You can take copy right patterns and make it your own just by adding your own special touch.
Lets talk pattern take a simple square break it down sevaral times and get several copy rights on it yes this has been done and this is why we have different patterns. So I take the pattern make afew adjustments now this pattern is min Did I steal, nope I borrowed it just like the rest of everyone and made the new improved pattern. "Love the led pencil & eracer"! It's the same with art. Copy rights and patents are only protected to whats written down or drawed out legally on doc. Take copy right of the simple nine patch,we have straight lines,curvy lines ect.....each one would carry different copy rights. These copy right documents are usually only carried out for twenty years,so the copy rights and patents have to be refiled over a period of time. This is my understanding,I could be wrong on the copy right but on a patent its correct,20 years. Another little example take the sweet little teddy bears the same person isn't creating these sweet little bears,someone is always trying to come up with better bears.
Along with quilt patterns,always looking for the new improved pattern ideas!(( So make it your own))
"Everyone " that has created something has borrowed to make it thier very own.
I learnt how to draw out my own patterns even with my very own sketches they have borrowed ideas by accident. This is with anyone, If you have a drawing starting out with a simple block,its borrowed because you were not The first person to draw out a block to quilt! LOL! ((So yes, Make it your very own))
We all borrow on copy rights to make our very own and thats why we have milions of different patterns developed through over the years.
Anyone got a cup of sugar I can borrow,I'm onto a new recipe!!!
