On the stove, melt butter on medium heat. Slowly add in marshmallow, stirring constantly. When all marshmallows are melted, add a few drops of green food coloring or more as desired. Remove from heat.
Continue to stir, while adding in cornflakes. Keep stirring until all cornflakes are fully covered with green marshmallows.
Cover hands with Crisco and shape green cornflake mixture into tube and wrap around to make wreath of desired size. Place 5 red hots on each wreath and let cool for 2 hours on greased cookie sheet.
