There are loads of Reindeer poems around on the internet, this year I've chosen the following one (printed out on white paper and then cut out).
Sprinkle on the lawn at night
The moon will make it sparkle bright
As Santa's reindeer fly and roam
This will guide them to your home.
Then attach to a brown paper bag and cut out a little felt reindeer, christmas tree or star to place beneath. The reindeer was actually a template out of my Japanese craft magazine (current issue of Cotton Time) but in the past I've downsized kids Christmas colouring in images to use as my template - there are loads available online if you don't have a book at home.
Wish me luck - I'm making 26 of these bags for Bella's class this year :O))
