With technology changing so quickly and new products and new techniques being introduced, we can never know all there is to know about design.
I completed my qualification in interior design 14 years ago, before setting up my business. Since then I have continued to learn and have added more qualifications - in kitchen design and personal colour and styling.
I have always had an interest in personal colour and wearing colours that make you feel good and suit your colouring. It is just an extension to the "holistic" approach I have to my work. If you feel fantastic and what you are wearing expresses who you are then it's only natural that your home should follow those guidelines. How many of us live like this?
If someone compliments you on the colour you're wearing or your clothes then they are not working for you. However, if they compliment you on how fantastic you look then the colours and the clothes are working for you. In one the colour or the style is noticed and not you, and in the other you are noticed because you look great in what you are wearing.
