In the kitchen I found some mini marshmallows that I normally use for baking and a cake pop bag (you can use any small plastic bag)
I folded a small label out of card and drew the design I wanted
Then I stapled the label to the little bag of marshmallows
And there you go! A little kit of hot chocolate and marshmallows ready to be wrapped up in a paper bag or some fancy patterned wrapping paper.
