Hi!
I am a demo for SU! It is true that you may sell handmade cards, etc. using the SU! images AS LONG AS you use one of the Angel Policy "hand stamped by" approved stamps. HOWEVER - you are not allowed to sell in any permanent retail location. You may not sell on a website. You CAN sell at craft fairs. I have sold handmade cards and other products at craft fairs using SU! stamps - and have done fairly well. Put out a mailing list signup and perhaps create a quarterly newsletter with information on what you are working on, what you are taking orders for, etc.
I have a friend who owns a scrapbooking and stamping store. She has other contacts of people who own stores and sell handmade items. However, Stampin' Up! does not allow me to sell handmade products at any of these locations.
If you are interested in getting your information out there (for selling handmade products), I would recommend doing what Rachel did - create a flyer or business cards describing what you do - but do not use the Stampin' Up! name or any of their designs on this flyer/business card. Get approval - better to be on the safe side.
Just my 2 cents.
