The good bread knife is definitely in a drawer. You can picture the drawer, and the tea towel folded on top of it. You are less certain which house it is in.

This can happen with a family holiday place, a room at a parent's home, or belongings split between a flat and a storage unit. You remember owning the thing. The address is the part that slips.

Packing from memory makes this harder. You bring the spare towels because you cannot remember whether you left any, then arrive to find a full shelf. Meanwhile, the one thing you were certain was there has come home with someone else.

A short record for each place gives you something to check before you pack. The best time to make it is while you are there, with the cupboard open.

Separate what stays from what travels

Make a short list for each place. Begin with the things that cause uncertainty before a trip: bedding, chargers, kitchen equipment, outdoor gear, and anything expensive or awkward to bring unnecessarily.

Give the locations names everyone recognizes. For something stored away, add the room and container. “Holiday cottage, bedroom cupboard, blue bag” tells someone where to look; “away” does not.

Then keep a separate packing list for things that travel. If a laptop always comes with you, it belongs there. If walking boots normally stay at the cottage, they belong on that home's list. When you bring them back for a few weeks, note the change.

Keeping these two lists distinct helps avoid an easy mistake: assuming that owning something means it is already waiting at your destination.

Itemsbase is a home inventory app for keeping track of your belongings, including things spread across more than one home. You keep a record of what you own and where it belongs.

Each home can have its own inventory in the app. Itemsbase calls this a Location. You can search across your Locations together, so looking up the walking boots tells you which home to check before you pack.

Decide which duplicates are worth having

Moving every small item back and forth can become tiresome. Keeping a few basics at each place may make visits easier, provided you use them and have room for them.

Choose deliberately. A pair of kitchen scissors you reach for every visit is a different decision from a bread maker used once a year. You might duplicate the first and move or borrow the second.

If relatives use the same place, check what is already there before everyone buys their own version. Add the item to the house list once it arrives.

Leave a note for the next visit

Before leaving, think about what will matter when you return. Note anything you took home and anything you wished you had brought, with enough detail that it still makes sense in a month. “Lamp for the back bedroom” is easier to act on than “lamp.”

At home, give those things a place to gather before the next trip. Keep the travel list with them, because the laptop you are still using will not be in the pile.

For a shared house, keep the handover somewhere the next visitor can find. They need to know that the spare duvet went home for washing, or that the camp stove is no longer in the usual cupboard. A photo from an earlier visit cannot tell them that.

Next time you pack, check that note before filling the car with things that may already be waiting for you.
