here are some tips for decorating your builds
Use different types of blocks
If you use different types of blocks for your builds, they stand out more and just look nicer. Some combinations I like to use are wood with limestone and stone with gravel.
Color things with paint
You can make paint at a mixing bench and use the paint to color blocks! You can use different colors of paint to really make it stand out.
If your builds are in a unique shape, then they will look very nice to look at.
You can use shelves or display cabinets to show of items that you put in them. You can use this to categorize things or let people see your favorite items.
Almost every block in the game can be made into stairs at a builder’s bench. Going up stairs is faster than going up ladders so use them if possible
Signs are a good way of showing what a room if for. Also if you are on multiplayer and have a shop then you can use signs to give your shop a cool name.
Experiment with different blocks, color themes, shapes, and displays until you find something that looks good!
