Well, in my last post, I showed a card for my uncle. I used a technique on the stamped image called "masking."...
First, get a post-it note (or some type of repositionable adhesive on the back of a paper) and stamp your MAIN image on a piece of regular paper. Trim around it very closely.
Second, stamp your MAIN image on the cs you want to use for your project. Put the post-it note stamped image directly on top of it.
Third, stamp your BACKGROUND image on and around your main image.
Fourth, take off the post-it note paper. Your main image remains untouched and looks like you got a completely different stamped image.
Last, color your MAIN image as you wish.
