Receipt Roll Letters

At work recently I was changing the receipt paper in one of the machines that claimed to be empty. I was surprised to find there was still a good three or four feet remaining, so instead of tossing it out I thought it'd be good material for a (rather unusual at the very least) letter. :)

Hopefully the post office will let it through. I put it in a regular envelope all rolled up, so it might have too much varying thickness. I guess we'll see!
