Blue Striped Laptop Cozy

I made this a while back to protect my laptop when I was carrying it around in my backpack and it served tremendously. I made it with half-double crochet stitches and a 2mm hook so the stitches are incredibly tight and the case barely stretches at all. There is no strap as it is meant to be more of a protective case than a carrier, though it also includes a pocket on the front to hold your charger.
 
This was a perfect fit for my 17" HD Pavilion, which was a pretty huge computer, so it should be suited to most other varieties of laptop. Contact the seller if you have concerns about size.
