Since they’re visually similar though the construction is quite different, is it possible that ‘brightly’ is a generic name for a particular style of quilt?
Like a ‘log cabin’ quilt isn’t the name of a specific pattern, it’s more of a style that can be achieved in many different ways. Or a ‘lone star’.
i can’t imagine Sherri doing anything that even smells like infringing on someone else’s work. It’s either a crazy coincidence, or there’s some other explanation.
