My Macbook needed a home. Less than half a yard of black fleece and some white felt later, the mac cozy was born.
It fits snugly like one of those pricey neoprene sleeves, but was a lot cheaper to make.
I thought it needed to match and have its own little apple, if you couldn't tell. This solves the problem of throwing my laptop into one of my tote/messenger bags and not worrying about having my stuff scratching up my computer.
