The Next Generation Stamps
For these two flowers, I inked my stamp with a dark red ink. After stamping, without re-inking it, I stamped the second image. This uses the same color, just a lighter shade of it.
This is a great technique for saving time and energy, plus you don't have to color match as you work. Because it's the same color, each generation will be in the same color family.
If you've inked really well, you can even do a third generation, one that's very light and very beautiful. Stamp a couple of times and cut them out, then stamp a couple more on the paper itself. The variety of shades will add some visual interest because they all go together.
