I would like to do more giving of home preserved products such as jam and salsa but the cost of jars holds me back. I wouldn't mind so much if I knew the jars would be reused but most that would be receiving these gifts would probably put them in the recycle bin or throw them away. I was thinking of printing a sticker to put on the bottom of the jar asking that it be returned to me when emptied. Is that tacky? How do you handle this?
