Share a favorite everyday item with the other person

Okay, I’m just spitballing here but thinking about what would make me feel welcome and excited to merge households with a new partner:

Could you each either pick your own favorite home thing, like a coffee mug or candle or pillow, OR have your partner go through your things to pick her favorite, and then for the first month, it’s exclusively for her use. So like she picks her favorite of your coffee mugs, then it’s hers to exclusively use for the first month. You wash it when it’s dirty so it’s ready when she wants a cup of coffee or tea again, etc. She does the same for you. Like a little warm welcome into how caring and sweet shared life can be?
