When my husband was getting ready to give his old laptop to his mother, I thought "You can't just give it to her naked. It needs some kind of protective sleeve." But I didn't want something boring, or worse - UGLY! I had seen the Monster Laptop Sleeve
and thought to myself that it didn't look to me like $65 worth of fabric and sewing.
I'm genetically predisposed to look at things and figure out how to make them myself for less, so of course I looked at this and said "I can do this!" Except that the more I looked at it, the more I realized that I didn't just want something fun, I wanted it to be reversible. Twice the fun!
I'm not good at sewing, and I'm terrible at visualizing things in three dimensions, so making it reversible took a lot of trial and error to get that part right. I did two - one for me and one for my mother-in-law. The one for me was my beta, and I ended up re-doing it at least twice. I took pictures of my mother-in-law's, once I was sure I'd gotten the kinks out of my process.
