Gridded wrapping paper

Khoi Vinh has a great post on an innovation introduced by Hallmark: gridding on the back of their wrapping paper.

this is a marketable and genuinely helpful innovation that, all told, can be summed up as almost purely a product of design thinking. Hallmark took a very simple product that had been in use continuously and without complaint for decades, identified a problem that everyone encounters and yet no one has taken seriously, and then created a wonderfully elegant solution for it.

Considering how crooked my cuts were last time I wrapped gifts, I know I could use this myself. Congrats to Hallmark on this one.
