Just go back to being a child and think like a child....when doing this tech.
Stamp an image on your cardstock, Don't color it. But take a piece of scrapbook paper or Basic grey paper and stamp with same stamp and then cut your image out.
Then take that cut image and glue it to the Cardstock, in the same place that you stamped before. It easy and fun!
another reason to like this tech is it gives you a great look. That you can not always get with pens, markers, inks and so on and on.
Just have fun!
Here's one I did a while back. using this tech.....
