Hearts and Blocks Valentines
1. Press the cookie cutter into an eraser to make a heart-shaped stamp; use the utility knife to cut out rectangular and square blocks, which can either provide a background for the hearts or serve as the main design.

2. When planning designs, experiment with color and form: Try complementing pink with neutrals and greens, or use pale-colored ink on dark paper. Combine shapes in unexpected ways to create elegant effects: A silhouetted heart surrounded by color blocks, for example, suits the space as nicely as hearts in rows.
