Introduction: Snow Farm
Step 1:
Put several fences around a block of dirt that is raised above the ground but leave a hole for you to go in.
Step 2:
Make a snow golem on the dirt block.
Step 3:
Make sure the fences are high enough so the snow golem can't escape.
Step 4:
Dig the snow that is under the snow golem to get the snow. Make sure not to hit it or it will die. Doing this is a lot faster and easier than waking around looking for snow.
