Monster Model & Laser Works has created some outstanding cobblestone sheets to follow their groundbreaking lasercut brick sheets in N scale.  The Sett Stone pattern is available in 1.87″x3.8″ (Scale 25’x50′) interlocking sheets.  The interlocking pattern makes seams virtually invisible and allows a road surface as long or wide as needed.  The Cobblestone Sheets are available direct from Monster Model Works.
