My sister fell in love with this tutorial for a zippered laptop case posted from Crap I've Made. I gave it a whirl and whipped one up for her last Christmas. Since then, I have been persuaded to make a few more as gifts.
The end result is a lot of fun, but definitely tricky to get everything lined up and fit together. If you can't wait to try this one, make sure you use a home dec fabric or thicker cotton. If you decide to use a quilter's cotton, interface the main panels. I also fused the fleece to the lining for more direct padding.
