Today I needed to explain to Little E via text
the very sophisticated measuring system I use
when a measuring device is not available.
I use this system frequently and usually have a folded bill in my pocket.
It would have taken a lot of words and typing to explain
so I folded my dollar bill,
took a picture with my phone
and then did the lines and writing with the markup tool on the phone.
Obviously, I could use more practice, but for today I think it served its purpose.
Thanks to M for showing me that the markup tool existed.
