1 ~ Whether your preferred look is rustic, modern, design, urban or country... you can create that personalised touch by utilising elements already in your possession. I love mixing old and new; vintage and rustic.
In this picture the only 'new' piece is the lamp which I fell head over heel in love with. Bought at a local homewares shop. The distressed mirror (one of my favourite pieces) was found at the local tip by my husband. The blackboard in old frame was made by him. The display cupboard, a find which was restored both by my husband and I (cut tin inserted in doors) - distressed paint and choice of black iron handles by me. I love Toile de Jouy and use it often in my house. Here the curtains which I made from original French toile purchased online and toile cushion made by a local artist sewer in Kangaroo Valley. The things you love are what make your décor speak of you.

 2 ~ Avoid mixing too many colours; the right yellow in the right amount in a décor with a dominance of greys, can bring energy across.  Here I introduced a yellow toile lampshade and a single yellow cushion to give a spark of mustard (my favourite colour!) against a grey backdrop. I threw a bohemian/tribal cushion in terracotta/grey/green colours as to give the room a relaxed boho chic look.
Get to know your colour palette.

3 ~ Draw some inspiration from magazines or designers but avoid "copy-paste" as it voids immediately your personality. And this is where the fun and creativity comes in when you can see reflections of your own style in the décor. Unique and personal, which nobody can reproduce 100%!

It is your home, your safe haven. You can express what you love and go fearlessly. Don't stick to styles but blend all the styles, the colours which speak to you. Be creative. Be free. 
And if this sounds too terrifying to explore or you just can't be bothered because it is not your area of expertise or interest at all, call me and I will come and work the magic in your home for you.
