Oh, procrastination. How I love thee. It's usually not difficult to find things to do while procrastinating. But if you need an idea, how about playing with these amazingly awesome Origami Sticky Notes?
A pad of these sticky little wonders is under $4, which really isn't much more than the boring pad of post-its you usually buy. Each pad has instructions for 10 different shapes, including: pig; penguin; boat; crane; butterfly; squirrel; lily and water bomb. Being the pig lover that I am, I'm fairly certain that crafting the cute lil barn animal will be my shape of choice.
This is the type of thing that anyone would love to have. It's a good gift for someone you don't know very well, but feel like you need to get them something. Or maybe as a little reward for a job well-done to your fellow workers? Of course you'll also need to get yourself a few pads to doodle on.
Personally, I plan on using them to pass notes, middle-school-style, with flair.
