The Slutsk sash is a four-metre ribbon of gold-threaded silk that once cinched the kontusz robes of Polish-Lithuanian nobility. Woven at the Radziwiłł-funded Persiarnia manufactory from the 1730s onward, each sash bore the Latin signature of master weaver Jan Madżarski — an Armenian craftsman who fused Persian botanical motifs with European Baroque sensibility.

This design system channels the museum vitrine where the surviving sashes rest today: warm taupe ground, deep crimson end-panels, antique gold thread catching low light. Typography in Cinzel small-caps echoes the woven inscription; EB Garamond carries body text with the gravity of 18th-century Polish printing.
