We've had our iPad2 since late last year but I managed to make a case only today.
Installing a zipper is always daunting for me, hence, the delay.
The outer cover is denim lined with fusible fleece. I printed out an Apple logo and used it as a template to make my applique.
The interior is quilting weight cotton lined with light fusible interfacing. I used a continuous zipper cut to length for this purpose. As with my other recent projects posted here (cosmetic bag and travel wallet), I opted for bias binding to give the cover a nice finish.
Most handmade iPad cases I've seen around are simple sleeves or zippered pouches (like large cosmetic bags) so I hope this gives you inspiration to try out something different. Elastic corners to hold the iPad and all around zippered closure for maximum security!
Thanks for looking!
