Step 1: What's the problem?
How are you supposed to focus on your next funny comment in a forum thread when your computer keeps getting pulled into your nethers? With this quick mod, that's how. So let's get started.
Step 2: Find your comfy spot
Now mark the spot on the Snuggie at the bottom of the laptop.
Step 3: Position netbook on snuggie
Step 4: Make more marks
The goal is to make a couple of slits that can become pockets for the netbook to rest in. So visualize a diagonal line going across the corners of the netbook and mark the spots where that line would extend off of the netbook.
Step 5: Cut!
Now cut lines between your pairs of marks.
Recommended, but not shown: reinforce the holes by sewing around them.
