my favorite furniture set is the Rococo set because it's very customizable and it looks amazing. This set really should've been a Gracie set in my opinion but I'm not complaining
The minimalist set! I'm using some of the pieces in the kitchen, bathroom, customized green in the doctor's office... it's super versatile. I'm also making heavy use of the gorgeous set, particularly the counter, stool, and lamp. The cabin set is always good if you want a more rustic feel.
The lovely set... I normally don't like to use a whole set..since I like combining sets...but with the lovely set... I feel the need to not combine. It's been my favorite since wild world.
I love the exotic and zen sets. I'm currently using the exotic set for my living room and the zen low table for an accent. I love mixing different types of wood pieces together. I also like the classic set when customized to chocolate. The Welcome Amiibo natural set is also really nice when used with other sets!
I'm fond of the Rococo, Classic, and Regal sets. Even though my town is going to have a modern theme, I'm still using one (or maybe more) for my house.
