Snow (the kind thats sort of hard and good for packing, or the snow that's there during springtime that's like ice.
Plastic Bag (maybe 2 )
Small Scoop (or your hands)
Shovel (for moving snow because your small scoop won't do it)
Step 1: Get Snow
I recommend that this is done on cement outside or other hard surface.
Make it as deep and wide as your cookie cutter with some extra on the sidesand top.
Flatten your pile with the shovel.
