Ever rushing out on a trip and realize you need a laptop sleeve like one of these chic styles? Or sometimes you're just trying to get out the door when you don't have a laptop bag or sleeve handy, and you need to slip your computer into another bag — and you don't want to let it bang up against the other contents of your bag.
For those times, hit up your linen closet for a pillow case. Slip your computer into the bottom, fold the excess fabric over, and bam, slip that into your bigger bag. It's not heavy duty protection, obviously, but it'll shield your laptop from superficial scratches and dents.
This is especially great if you're carrying on your laptop for a flight but don't want to carry it in a separate bag (especially now that so many airlines charge you to check any bags), or if your laptop sleeve's padding takes up a little more room than you'd like. Easy, clever, and not even as low rent as using a sock as a camera case.
