For any designer, I think it is important to have a way to present your work to clients. Though you could have a portfolio on Facebook or Flickr, I believe that the best way to present your work is to have your own website. Every deigned should have a website that they can use to display their work and advertise their business. Because the website is part of the business, I think that it is important that the website is specifically designed to display your work in the best, most appealing way possible. I believe that the design of your website is just as important as the work, because clients won't just see the website as a way to display your work, but as a piece of work its self. The better designed the website is the better it is for the business.
Here is an example of a website that I thought was very well designed. It really stood out to me because of the little details that were payed attention to. I think that this company did a very good job at promoting the quality of work that the business is capable of.
Do you know of any well designed websites that you want to share?
