For my IPad I made a crocheted sleeve. I took the project in the airplane and by the end of the holiday the IPad had a snug cover. Actually it was very easy because I started with a chain of several stitches as long as the IPad, turned around and circled up with single crochets. When it fitted I made one side longer to make a flap as a closure. I used grey acrylic yarn from a Dutch dollarstore and used crochethook nr 4,5.
