Sharing a technique from when I used to teach. 2-tone paper with rubber stamp. 2 contrasting pieces of paper (e.g. lime/black). Rubber stamp the middle of one (lime) with same color (black) as the other paper. Cut the lime paper in half to the top of the rubber stamp, but leave a small margin around the outside of the stamp shape to the bottom, then cut remaining paper in half. Glue the stamped paper on top of the other sheet. An easy 2-tone eye-catching effect for multiple use - tags, journals, embellishments, etc.
