Thanks everyone! I tried both ways. The stamping and embossing the "Thank You" first worked best. I'm not patient enough to sit and heat set the VersaMark as long as it would need to be done. I tried twice to and it didn't work. I like the look of the VersaMark as opposed to the color background, otherwise I would have used that. Thanks again.
I've posted the card in my gallery. It's simple. Nothing fancy. I'm not quite talented enough for the fancy stuff yet.
