We love classic Post-It notes, developed by a 3M researcher who saw opportunity in a chemist colleague's flimsy adhesive, but they're no good for larger tasks -- sticky signs, charts, long lists, bookmarks for giant books. 3M has come to the rescue with Post-It Big Pads, a new line of jumbo sticky notes that top out at a comically large 22 inches square. Part conversation piece, part makeshift whiteboard, these supersized pads are sure to surprise and delight at home and at the office, or wherever a lot of stick–to–itiveness is required.
