I make these little mystery or surprise bags for raffle prizes.
I have also used them as little favors bag and I know that they would go great in loot bags or prize packets.
Kids aside these would be great to hold a small gift for your sweetie (that you can leave on a pillow or bedside table).
These small bags are made from a single sheet of paper that has the question mark printed on it.
The bags themselves are easy to form on either a small sturdy box or a piece of lumber. I have a PDF and tutorial to show how easy it is.
