For those who are interested to study interior designing, I've found a great website that can surely help you out. It's called School of Interior Design. Its main focus is to guide and eventually help interior designing students or those who are simply interested with the craft choose the most appropriate school and courses that would fit their lifestyle, their present needs, and their economic  
capacities. It is also a design resource and interior designing portal for those who are home and garden enthusiasts, who would want a tip or two in interior designing.
