Colored sugar (use food color to get the shade you like)
Cellophane bags (small)
Ribbon (in your choice of color)
Poke lollipop stick in the end of a marshmallow, lightly moisten marshmallow with water (just a little) roll marshmallow in colored sugar or sprinkles. Allow to dry, then place in cellophane bag and secure the bag around the marshmallow and tie with a colored ribbon. These are adorable and look just like a baby rattle.
