I got a new-for-me ($500!) PowerBook G4 and needed a laptop sleeve. Looking at them online made me think I could easily do that. So I headed over to MAKEzine and found all sorts of project ideas. People make laptop sleeves out of wetsuits, cable knit, an old sweater, and some weird stuff, like kitchen sponges. I settled on old pants, which seemed within my abilities. It's the kind of thing I can make with my very old Singer Featherweight. I'm very happy with it. I'm not putting up any step-by-step thingy because I wasn't nearly as careful and precise as the Sambot guy and didn't take photos along the way. I plan on making a velcro strap to go around the opening and a handle on the side for carrying ease.
