I got the most awesome 15" MacBook Pro a few months back & don't especially care for the black neoprene sleeve it came with. When I found this way easy tutorial on Skip to my Lou, created by Crap I've Made, I had to give it a try!
MacBook Pro has a marvelous home inside THIS laptop case. It's a much better use for the fabric than covering a small sedan, don't you think? :) Now what to do with the rest? I'm thinking luggage to match....we'll see.
