I'm a fan of fine crafts and decorative arts. I think it's been decades since I bought something like that in Europe, but I love looking around galleries that are essentially museums with price tags.
It's harder than one might think to get information about high-end craft galleries online. A lot of what turns up when I try an internet search is ordinary gift shops--some of them stores pleasant to browse for a while, but not places you'd generally go out of your way for.
The biennial craft exhibition in Venice, Homo Faber, will take place in September this year. I think that's a schedule change; I believe HF has previously been held much earlier in the year. This will be great because Glass Week is also in September. https://2024.homofaber.com/
On the Homo Faber website there's information potentially of use to other fans of contemporary crafts and decorative arts.
Fine-craft galleries: https://www.homofaber.com/en/galleries. I suspect this is advertising, albeit most likely curated, but I've been to a few of the listed places and know they're very good; the photos look solid, too.
There are also links set up to point to itineraries focusing on crafts/decorative arts in a number of cities. Unfortunately, at the moment all the links take you to information on Lisbon. I've reported the problem and assume the Homo Faber folks will get the links fixed at some point. https://www.homofaber.com/en/itineraries
A big thank-you to whoever it was who mentioned Homo Faber on the forum years ago. If not for that, I wouldn't know the exhibition exists.
