Marker making involves the precise arrangement of pattern pieces to determine the most efficient layout. Key considerations include fabric width and length, table size, and production planning. The marker efficiency percentage shows how much fabric is actually used. Efficiency depends on factors like the planner's skills, garment sizes, number of sizes, marker length, pattern engineering, and fabric characteristics. Methods include manual placement of full or miniaturized patterns and computerized optimization. Maintaining the grain line and fabric characteristics present constraints.
