A gigging drummer's kit adds road cases, a hardware rack, and sometimes electronic trigger pads to the usual shells and cymbals, so the packing job is really about protecting shells and keeping every stand's hardware bundled together by piece.
Pro tip: A soft moving blanket folded and taped inside a case lid adds cheap extra cushioning for a kit that gets moved often, extending the life of thinner budget cases.
Watch out: Never let bare metal hardware, lugs, mounts, or rack clamps, sit directly against a shell's finish inside a case; the constant contact during a bumpy ride is a common cause of scuffed or dented shells.
