Part 3 of our city series: a vintage California badge, engraved directly onto a denim tote with the ATOMSTACK SWIFT MINI. No ink, no vinyl — just the laser changing the dye on the fabric surface. Settings we used: Power 12 / Speed 3500mm/min / Line Spacing 0.1 / 1 pass. Always test on a scrap first 🧵 LA, NYC, now California — which city should we do next? 👇#ATOMSTACK #SWIFTMINI #LaserEngraving #CustomDenim #DenimArt
