Inspiration boards are a great tool to help you visualize and create the look you are going for in a room. If you haven't mastered a graphics program like Photoshop, I've found a much easier way of creating your own inspiration board on a website called Polyvore. Polyvore is a free web-based application that allows you to drag and drop items from your favorite websites to create virtual inspiration boards such as the Coral Vine board listed below.
Polyvore will save the board you create and it will also save useful information next to the board such as product description, source website and price.
Here's more information about how it works. The general layout reminds me a lot of Flickr. All in all I have found it very addictive, fairly easy to use and best of all...free!
