Glue candies to cone.
Beginning at the bottom, hot glue conversation heart candies to a foam cone.
Alternate the direction of the hearts, so they fit close together and hide most of the cone.
To preserve the candy cones, coat with Mod Podge or another foam-safe sealer.
Some spray sealers will dissolve Stryofoam. Always test first.
Store cones in an airtight bag or container.
