This is my first instructable, and it is quite the simple one! You can do this in under 5 minutes, and it is quite useful!
Step 1: Materials
The following objects are required for this tutorial.
• A standard sized wallet card (Don't use a metro-card or other thin card like I did, the stand ended up being quite flimsy...)
• A pair of scissors
• An iPhone
Step 2: Folding
Take your card and fold it length wise.
Step 3: Curve and cut
Use a marker to draw a curve much like the one in the picture, and then use scissors to cut along this line.
Step 4: All Done!
The finished product is shown below! You can fit this in your pocket or wallet for movie watching on the go. In the second picture you can see the better version of the stand, made with a thicker card.
