I am trying to figure out how much I need to fill my guests mason jars with Hershey kisses. The gifts were going to be mason jars to use while at the venue however my venue doesn't want glasses to be used for safety. So I changed them to mason jars filled with Hershey kisses. Has anyone done this before? Do you know roughly how many kisses it would take to fill a 16oz mason jar? I was planning to buy many party sized bags from Walmart but found out that they sell a bigger bag (400pc) and would like to buy that instead just don't want to buy too many.
