EASU: Sack or Bag?

Do you say sack or bag for the container you get at the store to carry out your merchandise? I never know...

For this swap you will create an ATC for your partner using a bag or sack somewhere on it. Obviously you won't use the whole thing, and it doesn't even have to be an actual bag or sack, but something that might be made into one, like brown craft paper, wrapping paper, etc.

You choose the theme, but somewhere in the envelope you send, be sure to say whether you call it a sack or a bag! Package securely, include swap name and your username for rating, mail on time, and rate promptly upon receipt.
