Consider design styles and experiment with color options and patterns. Enhance the lamp with accessories like lampshades and finials. Ensure safety by wearing protective gear and working in a well-ventilated area. Allow ample drying time and follow proper maintenance practices to maintain the painted lamp’s beauty and functionality.
