As for clarification, macros are found on the same place on a Windows computer.
Where you find something inside the Blockland folder will never change no matter what OS you use.
A couch that's pretty well incompatible with any colorset.
Just spray it however you like.
An end table to go with the couch, which you'll probably also have to spray.
Oh and a dog house without the 4 print bricks on the door. (Used too many other kinds of bricks)
To make couch: Make your ghost brick as 1x1 round, and don't rotate it. It builds from the front (your left) corner, to the back (your right) corner.
To make end table: As above, except the 1x1 round is the 3rd brick.
To make dog house: Set whatever is the biggest plate in the list as your ghost brick. Rotate CW (num 9 on numpad keyboards), and start. Open brick menu for 4 print bricks to put in the doorway, and use this for the name of your 'pet'.
