One of my steps towards this was to create a brand new Facebook page for Wear Me Jewels which can be found at: http://www.facebook.com/wearmejewels .
I did this on Wednesday and have some followers (27) which is a start. I am thinking the the facebook page could be a great way to stay in touch with customers, more real-time then a monthly newsletter. I is a wonderful place to add new items, offer coupons, etc...
I learned some things while setting up my facebook fan page. The first was that you need to have 25 subscribers before you can shorten your url to your business name from the big long number filled url that they initially give you. Once you have your first 25 fans go to Http://www.facebook.com/username to make this change. A shorter url is much easier to remember.
That's it for now!
