Fill as many mason jars as you want with the mint-flavored M&M's. 1 bag of Mint M&M's fills an 8-ounce jar about 3/4ths the way full so I use about 3 bags per 2 8-ounce mason jars.
(To cut down on cost if you are making a lot use smaller mason jars or a less expensive green-colored candy)
Tie a festive red ribbon around the top of the mason jar.
Using hot glue and a hot glue gun, glue the heart button to the right side of the jar (right from where the tie of the ribbon ends up.)
