I got tired of carrying around a stand or propping up my iPhone to watch shows so I pulled out a old ID card I had in my wallet and folded it to make a stand. Any hard plastic ID or old Credit card will work and they can be flattened again and slipped back into your wallet when you're done.
This is so simple I'm sure someone has done this before, but the more information we get out there the better.
Step 1: Pick a Card any Card
Get an old used hard plastic card like a old ID or Credit Card (please scratch out any sensitive info) I used an old college ID that i tore the picture off of.
