Room Shapes:
Did you realize that there are basically only five rooms shapes? They are square, rectangle, odd angled, bowling alley, and L shaped. Each of these rooms calls for a different furniture layout.
Odd Angled room: Use that angle to your advantage! Place your furniture such that it complements the angle in the room. For instance, if the angle includes a fireplace in that corner, face your largest piece (like the sofa) so that it directly faces the angled fireplace. Add in the remaining pieces, keeping them close. Voila! Cozy and ready for a good cuddle!
The main idea is: DO NOT IGNORE THE ANGLE!!
