inspiration comes from everywhere- without guilt! if you have no intention or need of using the pattern there is no reason to purchase the pattern- make your quilt as you envision your quilt- it is not an ethical/non ethical situation. you do not plan to copy her quilt- so- carry on. crossing that line comes into play when you see a quilt somewhere- take pictures of it then go buy the fabrics & copy it- making one just like it...it does not sound as if that is your plan at all.
