Write a route somebody else can follow
Name the object in everyday words and describe its location from a known starting point. “Large white platter, hall cupboard, top shelf behind tablecloths” is enough to guide a guest who has never stored it. “Platter with serving things” assumes they already know which cupboard holds those things.
Record temporary moves as well as the home spot
If several pieces travel together, give them one entry and an easily recognized container. Update the note when a piece comes back from a gathering. Otherwise a careful inventory can describe where something used to be rather than where the next cook will find it.
If the platter goes to a relative's home for a celebration, change the entry to the temporary location and name the return plan. Keep the usual home location beside it. Otherwise the next person may empty the correct cupboard twice before realizing the item is somewhere else.
Check usefulness during the next meal
Ask another cook to find the item using only the note, without a narrated tour. If they stop at the wrong cupboard, revise the identifying words. Add a photo only when a written description really misses a distinction, such as two similar platters of different sizes. Remove an entry once the household gives the item away.
