Gauge—the relative density of the fabric—determines the degree to which a magical object can utilize or redirect fields of energy. But magic often requires a mix of skill and sacrifice. It’s not enough to knit a pattern without making a mistake: you also have to give up something of yourself. A heart shroud is a complex spell, filled with twisty cables mimicking the structure of the human heart.””
