I like the Spooky and Rococo sets. I also like the Hibiscus Clock, Lily Record Player, Sunflower Stereo, Gorgeous Seat, Gorgeous Sofa, Sloppy Closet, Sloppy Stereo and Sloppy Table.
I dream of someday owning the Spooky set. I also LOVE the mermaid set, but not to completion because a lot of it is overwhelming - I think specifically the walls and floor + furniture but in pieces they are super duper pretty. I also love all of the ordinary 'dollhouse' furniture like the washing machine, dishwasher, ironing board, etc. I'm currently working on a room with that theme! Also the egg furniture. How did I not know there was egg furniture? Easter needs to hurry up so I can egg out. -w- Also, the mushroom set. Whaaat. I didn't even know that existed until HHD. Now? It needs to be mine. I also love all of the little indoor plants. I want an entire room full of plants. Jungle or greenhouse themed maybe? I am very passionate about furniture, waaaa!
I like Gracie and Kiddie sets. So vibrant, bold, and colorful.
sunflower stereo, alpine furniture, retro sink, and bonsai items are also nice and I would like to own them irl.
I wish the ice lamp can be customized. That thing can also work as ore lamps! That being said, I like the ice lamp too.
My most favorite pieces are the vintage telescope from Pascal and the cool globe. I also love the violet screen, lily record player, bottled ship and well, most food items.
Any of the Bonsai, the minimalist set (I have them customized to moss green), cardboard box, and... Maybe my train set and snow globe? It's kinda hard cuz there's so much cute furniture. But you can't go wrong with plants or instruments imo.
