Start decorating a bedroom with thrifted finds by embracing a slow-collect philosophy. Allow yourself a rolling budget over three to five years, aiming for a 70/30 mix of vintage to new items. Focus on high-impact DIY home decor hacks like painting vintage furniture the same soft color, organizing collections thoughtfully, and layering lighting with rescued lamps. This process helps build an eclectic vintage bedroom that feels warm, personal, and 2025-ready. Begin with one piece, style it intentionally, and add or edit items over time, enhancing your bedroom's soul and individuality.
