Recently I stumbled across a BILT brand bag made to hold chargers and cords, and I immediately knew that with a little modification it would be a perfect netbook bag for Asus's smallest model. I found two bags at an outlet department store called TJ Maxx each for about $10.00.
Step 1: Getting Ready
The bag is constructed out of neoprene fabric so it is already cushy and stretchy and will both protect your laptop and stretch to hold all your accessories. The bag is basically composed of two main compartments and each compartment has been divided into three smaller slots.
All you have to do is remove some of the stitching to create a large main compartment for your computer and modify the other second compartment to hold cords and mouse.
