Sometimes you purchase seeds because, you know, they serve a specific purpose. Food? Absolutely. Animal fodder? Sure thing. Pollinator attractant? Now we're talking.
And sometimes, that purpose is for...decoration. While these seeds are grown for their pepitas (pumpkin seed meats) I have visions of making gorgeous jewelry out of them. The edges are sparkly silver, for goodness sake. If that doesn't cry out to be made into earrings, I don't know what does.
