[header] How to accessorise your room [title] Decide what you want your room to appear as. [step] If possible, try not to go for a theme. You like lots of different things, so your room revolving around just one thing will only make things difficult! An idea is to have a base colour, namely on your walls, and other colours around your room. 
Make a plan of the way your furniture will be laid out too. If you want a theme go for a theme that covers a lot of different interests.
