A personalized paint set with high-quality paint brushes, perhaps in a beautiful wooden box would be a great gift for your friend who loves painting miniatures. You could also include some miniature figurines or a small painting canvas that your friend can paint on. You could also consider purchasing a gift card to a local art supply store, so that they could pick out their very own supplies. Another thoughtful gift idea could be a "brush cleaner" kit, which includes cleaning solution or soap, a cleaning pad or sponge, and instructions for cleaning and preserving paintbrushes.
