I bought the tissues at the Dollar Store. They came in a 8 pack for $1.
For girls camp every year we do a pillow treat each night for the girls. I came up with this idea last year and it went over so well, that we decided it will be something we will continue to do every year. We make sure that this is given to them the night before testimony meeting so that they come prepared. Usually, our tent leaders will incorporate our treat into a nightime devotional.
