Celtic Quatrefoil Knot Metal Sign

About the Quatrefoil Knot design

Each arm of this knot splits into two pointed petals that lean away from each other, so the outline carries eight sharp tips instead of four rounded lobes. The ribbon is drawn as a pair of thin black edges with a white channel running between them, and it breaks cleanly wherever one pass ducks under another. At the center, the loops cross in a small woven diamond, tight as the twist of a pretzel.
