Coaster set batch
120 ml pours across 6 pieces
A practical Etsy-style run where mica powder and a moderate 2:1 resin kit both matter to the final per-piece baseline.
Result: The batch cost is still manageable, but the per-piece floor is high enough that underpricing becomes easy.
Serving tray pour
420 ml piece with heavier decorative spend
Larger statement pieces make resin volume dominate quickly, especially when dried flowers or metallic pigments are included.
Result: Big pours feel premium, but material cost climbs fast enough that the batch needs intentional pricing.
Small jewelry batch
28 ml pieces across 18 molds
A tiny-piece workflow where low per-piece volume is offset by the fact that you still lose material to mixing cups and overflow.
Result: Small molds look cheap one by one, but the total mixed batch still needs a real materials budget.
