ONE more point about going PRO...if you are serious about it, then you must NEVER put a pix of anything you plan to publish on the internet..not even in your FLICKR type photo albums...
once it can be seen on the internet, it is considered published, and if someone snipes it, and can publish before you...well...it gets ugly...
also if you plan to do some magazine patterns first to test your waters...do NOT put pix on the internet or show at guild, nothing....any pix of it can lead to the same path as above!
People don't realize that when they post pix of their quilts that they are in fact "publishing" them. Many of the upper quilt shows now will not allow quilts that have been PUBLISHED...if they google your name or the quilt entry name and that quilt comes up, it is pulled...and not entered!
Don't you just love the internet???
