A excerpt from Lolly's blog-
"Just as the cardinal directions are linked to a color, each direction is also linked to a season, an element, and a natural material in many cultures. This quartet of features (color, material, season, and element) are a part of this cardinal direction. As a participant in Project Spectrum, you can choose to simply explore the colors associated, or even the textures of the natural material. If you choose, you can interpret the directions through the lens of the associated season or of the element. Your interpretations can be literal or esoteric. You can explore the science or the philosophy. Like the Project Spectrums of years past, it is totally up to you!
I think I will be doing a sock theme, I am on a roll so far this year with socks. I have some great green sock wool in the storage locker. I'll add some sewing, maybe a necklace, green is a recurring theme for me. Maybe even my coat for the great coat sewalong will be revisited.
