This is a fairly simple project and if you currently own an iPad you might not need to pick up anything at all.
Here's what you'll need:
- A neoprene sleeve designed for the iPad 2 or 3
- A pencil
- Your Nexus 7 tablet (for measurement)
- A fastener (velcro, a button or snap)
I was fortunate enough to pick up a neoprene from the local dollar store for a dollar and change, but you can find similar cases on eBay in various colors and at various prices.
If haven't already noticed the width of the iPad in portrait is almost identical to the landscape width of the Nexus 7. Take your neoprene sleeve and your tablet, with your tablet placed in landscape along the bottom edge of the sleeve and use your pencil to draw a line across.
Take your scissors and cut off all but about 2 inches of slack at the edge. This will give you a flap of neoprene you can use close your DIY sleeve (like an envelope). Cut into one side of the slack you have left, and cut across at the line you've drawn.
At this point, you have a sleeve perfectly fitted to the Nexus 7. If your comfortable with just tucking in the flap of the sleeve to close it, your work is now done!
For an added touch of protection you might consider adding a fastener to the flap to prevent your tablet from slipping out of the sleeve when you toss it into your backup. I happened to have some sticky velcro strips in my tool box, which would likely work well enough. You might also consider using a decorative button, or snap to finish off your case. Just be careful to cover any sharp edges on whatever fastener you use as to not scratch that lovely 7 inch screen.
