I have been listening to a great podcast about stamping. It is hosted by Susanne of So Suzy Stamps. It covers many different topics that are non technique such as how to develop your brand or interviews with people who developed there hobby in to a profession. SSS has been mentioned several times.
I would encourage you to check it out. Great think to listen to when you are creating.
I am not affiliated in anyway just wanted to get the word out because I thought others might enjoy it.
