Here is my entry for a padded laptop sleeve that recycles a sheet of foam packing material and uses about a half a roll of duct tape. The project only took about 2 hours and the end result is a pretty sturdy cushioned sleeve perfect for your eeepc or any other laptop you want to protect.
Step 1: Materials List
Cutting knife ( I recommend a snap-off blade knife)
Sheet of foam packing material (I recycled mine from a package I received)
