Most coffee places nowadays provide with a cardboard 'sleeve' when you purchase a coffee to-go.
A lot of the times these sleeves go to waste after their usefulness is outlived. i.e. the beverage is no longer hot.
I decided I could use one to turn it into a cheap (free!?), portable iPhone or Smartphone stand at my desk.
This is the most affordable solution I have found ;)
Step 1: What You Need
1 - A coffee sleeve
2 - A pair of scissors
3 - A writing instrument (optional) - a pen, pencil, marker, crayon, etc.
