Maiden Castle's ramparts set ring inside ring, smoothed by centuries of grass. Concentric black bands hold a pale centre, the outline wandering freely, crossed by a single dark stroke as the one deliberate break.

• Concentric rings: black bands around a pale field
• Single dark stroke: one off-centre break in the pattern
• Two pile heights: hand-tufted in Jaipur so the black holds its depth
• Wandering outline: an object first, a rug second
• Best placed: beneath a Georgian cornice or bare concrete, or in a hallway
