Favourite little shops or markets in London for unique finds?

Hey everyone! I’ll be in London for a few weekends and really want to check out some small shops or markets with a bit of character, places that sell handmade items, vintage bits, or just those little things you don’t see everywhere.

I’ve already been to Camden, which I liked, but I’d love to explore other spots that have that same creative or slightly quirky vibe. I’ve always loved collecting small, meaningful things from different cities, could be handmade jewellery, retro posters, local ceramics, anything that feels special to the area. Would appreciate any recommendations!
