I seem to run into problems putting my screen name on the outside.
I get the package all ready to go and hand it off to DH because he's got a online postal account and does it while I'm at work. Normally I never see the package once it is closed up.
First package I wrote it right where the label needed to go, so had do it again.
Second time I put it lower down, and ended up putting it right where the flap covered up most of it once the package was sealed.
This last one, I think I put it in 2-3 places to be safe!
