Stephanie from The Crafty Kitty shares a tutorial for making her Padding Organic Canvas Laptop Sleeve. The padded sleeve has a open top with two button tabs to hold the laptop inside. Her tutorial shows how to make it to measure so it will fit any size laptop. You could also use this same style sleeve to carry a tablet or reader. Go to The Crafty Kitty for the how-to.
