wc crayons. If you stamped it in black ink, there would be a much harsher look. I even used a gray (Versafine) ink for the title and background stamping as I wanted it soft.
Watercolor crayons.....they are my friends!
I was at a show selling Rubber Stamper Magazines and a stamp company from Florida (now closed) was selling Faber Castell crayons....I asked the guy that if I demoed the method at my booth (to show examples of what was in the magazine) and sold crayons for him, would he give me a break on the deluxe set....I did such a great job selling that he had none for me to buy at the end of the show! I eventually got them, but that is what you get when you are passionate about something....just joking!
