To create a home that looks like it is out of the pages of a magazine an interior decorator is your best bet. If you have the opportunity to use an interior decorator and you have never worked with one before then you will want to familiarize yourself with their value-add and also some of the potential downside.
When your interior decorator charges you retail price, but they get a discount is known as cost plus pricing. The difference in the price becomes the designer’s fee for service. This may work for you, however if the designer has really good connections and gets large discounts then you may be paying them a lot more than if you choose a different fee structure.
