This you need to know boss!
To craft decorations, you need to collect Blueprints. Blueprints can be found in the Special Delivery Crates or sold to you directly by the Merchants. Completing Chillout Events will also get you a lot of Blueprints!
Each decoration requires a certain amount of Blueprints in order to build it
Each Blueprint allows you to craft one type of decoration such as a piano, jukebox, aquarium etc..
Head to your Design Studio catalog, this is where you can see what Blueprints you have and which decorations you can craft.
