Okay, picture the classic Triquetra — the Trinity Knot — sitting right in the middle of the back. It’s one of those symbols that feels timeless, representing cycles like life, death, and rebirth, and when it’s placed along the spine it really plays into that sense of energy flowing up and down your body. It’s elegant and kind of quietly powerful, like a secret you carry on your back.

This one pairs traditional knotwork with a bold raven silhouette, and the contrast is gorgeous. The knot sits in a braided circular border, symbolizing protection and eternity, and the raven below spreads its wings like it’s guarding the whole thing. In Celtic myth, ravens are connected to transformation and messages from beyond — so the whole piece feels a little mystical and a lot intentional.
