DIY Project - T-Shirt to Laptop Case

I'm not really a fan of clothes shopping, but I did have a recent buying binge of Internet t-shits, because I have a difficult time resisting a clever slogan. Alas, I have a Big Girl Job, which means no t-shirts at work for me (no matter how much I whine and plead), so my "Shakespeare got to get paid, son" t-shirt is doomed to languish in my closet, only to make my wearing rotation on the occasional weekend afternoon.
If I were a craftier sort of gal, I could follow Voxphoto's example, and make my t-shirt into a functional laptop case. Maybe I can't wear t-shirts to the office, but surely they couldn't complain in my laptop came in wearing the latest Threadless T?
