The computer originally came with a nice black zippered sleeve and you can still use it with this case for added protection.
I originally bought the IKEA bag for my larger Sony Vaio but the bag was a little too short for the laptop to fit comfortably. As a result, the bag eventually ended up in a closet. When I got my new eee pc, I started to shop around for a nice travel bag. What I found though is that most of the bags out there are too big or if they fit my netbook there is no room for peripherals, like my mouse and all those cords.
Suddenly I remembered my IKEA bag and thought maybe I could customize it. For free.
The following steps take you through my journey.
Step 1: Disassemble the bag
Take apart the bag. This took a while but well worth it. There are many parts to recycle for the project and I only used parts from the original bag. I didn't have to add any new hardware or fabric.
Here are are all the components.
Step 2: Measure your netbook
Fold up the bottom edge up and place your computer on top. Don't worry if the fabric seems narrow. You're going to sew on side panels in the next step.
Determine the amount of the turn up. I made this a fold little longer than I needed because the original bag has a nice ready-made feature which I wanted to keep. It has a zippered compartment, which is perfect for my cords and mouse.
I cut away about 10.5 inches from the flap end of the bag.
Step 3: Resize the side panels
I trimmed the panels to about 2.75 inches wide and the padding to about 1.5 inches wide. The height of the panels is about 10.75 inches. All these measurements are before sewing and include a seam allowance of about .25 inches.
For ease of sewing I basted the layers together.
You should calculate these measurements based on your netbook size and how wide you want the bag to be. You could easily leave the panels in their original width. Any narrower that about 2.5 inches will make it harder to sew along the bottoms and make the shoulder strap a little more difficult to sew on later.
I wanted my computer to fit snugly but not too tight. As a result these measurements are based on careful observation and using my netbook as much as possible to help determine correct size and fit of each element.
Step 4: Sew the panels to the body of the bag
Attach velcro tabs to the inside of the front flap, matching them to the velcro tabs on the main body of the bag. Baste the front flap layers together. Do this before attaching the seam binding.
Step 5: Finishing the edge
Before you pin the binding on decide whether or not to round-off the front flap. I trimmed the corners on mine to match the original.
At this point you can stop and use the bag as is, or you can create an additional padded liner and a shoulder strap. These are explained in the next two steps.
Step 6: Sizing the padded liner
I cut off the bottom of the padded liner, pulled back the fabric and trimmed the foam padding to size. I then pinned the fabric in place and sewed it back together, making a box at the bottom end. This looks complicated but I basically recreated what was already there. I just shortened it to fit the bag and cleaned up the edges.
The liner just slides in, if needed, for extra protection. This step can be left out though. The bag would work really well without the liner.
