Make a hot cocoa mug!
I love this gift idea and I have given variations of it a number of times. It is quick to put together and great as a coworker, teacher or neighbor gift.
Grab a Christmas themed or even a plain red mug. You can find them super cheap at thrift stores and at the dollar store too. Fill it with two or three packets of hot cocoa mix (or your own homemade).
Add a bundle of miniature or Christmas shaped marshmallows by simply placing a handful in the center of a square of cling wrap. I've even sprinkled in some chocolate chips with the marshmallows. Then pull the corners together and tie with some curling ribbon.
Tuck in some mini candy canes or peppermint candies and you're done. I like to set the filled mug in the center of a large square of clear or colored cellophane and tie it up with ribbons and bows too, but more cling wrap or even those treat bags they sell at the dollar store will work just as well.
For the adults you can add a mini bottle of peppermint schnapps. Yummers!
