These pop-up cards are called “ink free” because no printing is visible on the completed card — the image is created by the paper alone, buildings, people animals or shapes appear without a single stroke of the pen.
Of course these printable templates are not literally “ink free.” The cut and fold lines are drawn on the reverse of the page. You can also color, draw on and decorate these cards with as many techniques as you choose. Or cut them out of colored paper. The only requirement is that you experiment and have fun!
