ok so i found a pattern to a bag i really like making. its' a japanese knot bag. If i make these with her pattern i can't sell it. If i were to re-draw it with my changes and personal touch. (the original is round, i want to make mine square) can i then sell this? i don't know how that works.
That should help some. I have researched this before for Cross-stitch patterns.
There are a lot of websites out there that outline most of the laws about the copyright of patterns.
