Call it a design board, call it an inspiration board, call it a visual aid. The bottom line is it should help you visualize the room of your dreams. I use design boards for all of my personal design projects because they are great for keeping me organized.
The point of a design board is to get you started and to create a tool in which you can use to help achieve your desired end result. Your board will include resource information, color suggestions, furniture lay out tips, and anything else that will help you start (and finish) that decorating project. There is a minimal fee for these boards but my design tips will work with a range of budgets.
