Good plan. Add a default rule and response window so you’re not stuck waiting: each Monday send your capacity and current queue and say you’ll prioritize customer-facing items unless they reply-all to reorder by noon and for collisions, use a reply-all note with a clear tradeoff and deadline to decide, e.g., “I can deliver A today and B tomorrow unless I hear otherwise by 12.” If they want fewer pings, suggest a rotating weekly DRI so one person breaks ties.
Totally agree that paper and keeping pieces out of sun make a big difference but it also starts with choosing lightfast pigments. Look for artist-grade paints with ASTM I or II ratings and favor staples like ultramarine (PB29), phthalo blue (PB15:3), quinacridones (PV19/PR122), nickel azo or Hansa yellow (PY150/PY97), and earths like burnt sienna (PBr7), while avoiding fugitive colors like Opera Pink and genuine alizarin crimson. A small primary set from an artist line using those pigments will stay bright for years even before framing.
