I love decorating and now that I live alone I am in my element finding bits and pieces to make it look different.
In my living room, however, I've got a full wall mural of a walkway with columns down one side, metalwork over the top and trees growing over it, with lots of pink flowers and lime leaves. It is very striking and beautiful, well, I think so. So the rest of my room is olive green on one wall, lemon/lime mix on another and bright pink on the chimney breast. Other than that I am going for an oriental look in here, with Indian cupboard knobs, oriental lamps, cushions, throws and a rug. Very colourful. I don't do Kelly Hoppen! Beige!
My stairs are carpeted red and I am putting emerald green with it, paint, and a light reflecting paint in light coral. With that will be stickers of butterflies going up the stairs, voiles at the window and wall decals.
The kitchen has gone retro. Very in just now, apparently. I have a new light box which I can change the words on depending on what mood I am in, it currently says "Party, Love, Fun" with smiley faces and cake.
Bedroom not much change, just change of bedding as darling son thought nothing of snuggling under my duvet so wanted new, not teenage smell. 
Bathroom, new shower curtain in pinks/purples/teal with birds and butterflies on, small coloured glass bottles on windowsill, mirror repainted in curtain colours, new bin, bits and bobs, new storage drawers instead of the ones I have had since I was this big. 
It doesn't need to cost a lot. Just a rug which is colourful and then pick out the colours in it to do the decorating. I like looking at magazines but I get my ideas by trial and error really. Working from one piece and then finding things around it and seeing it grow. I love it.
I do have two throws stapled to my wall in the bedroom as I wanted different textures in there and warmth as I don't put the heating on in my room. Along with rose wallpaper it makes it warm and cosy and feminine.
