Viag..! Oh, bummer.
Well, I habitually split my paper napkins into halves or thirds, depending on how much I think I need.
Also, another FYI is that some inkjet printers out there are capable of printing two sides for you, but you may or may not have to buy an extra attachment to do so. I had an old printer once that did that. The attachment wasn't cheap ($80), but I felt that the financial and environmental benefit, as well as reducing the overall paper clutter, far off-set its cost.
Speaking of which, the ink on many of the popular brands (*cough* HP *cough*) are rather expensive to print per page. Other brands such as Canon, with their individual tanks, and off-brands such as Brother, costs even less, or is at least better at reducing wasted ink.
Laser printer cartridges may seem quite expensive, but overall, their prints per page may come out to be cheaper still. It also helps that personal laser printers are now as affordable as personal inkjet printers.
Personally, I don't even have a printer right now. I just don't seem to have too much printing needs, and if I do, I'll just have it printed at work. No printer means no cartridges or paper to pay.
