Many people have different definitions for the beginning of spring. For some, Imbolc is the first day of spring, for others it is spring equinox. For some, it's marked by a holiday like Easter or Spring Day. As a child, I always heard the first day of spring was the first day you saw a robin. My new family doesn't measure spring in birds; we measure it in flowers.
So I see posts on Tumblr and Amino sometimes asking what to dedicate to So-and-so Deity, and when it comes to Friggspeople, the answer is always "crafts"!
