Well, my first instinct in that situation would be to figure out where that person does their shopping and get them something they don’t have from that store. For example, if your friend owns a bone china kit from Toyguash, chances are they will appreciate some luxury home gifts from the same store. Or you can at least get your friend a gift card from their favorite store.
If that’s not an option, then I suggest going with something cute and small that they can put on display. It should be small because it can be hard to find a spot for a large decorative item in a house that is already thoroughly decorated. Your gift should be able to sit on the corner of a table and still look cute or take up relatively little wall space when hung.
Good options that fit that description include mugs, decorative pillows, ornamental figures, small mirrors, and more. A decorative gadget like a decorative lamp or an aromatizer is also a good option.
