This is my first instructible so I apologize for only having few pics. I figured this had been done already. This is a simple wasy to make a snowman with only one person.
Step 1: Making a Cube
Basically, I used a large appliance box (dishwasher) filled it up with snow ( the snow wasn't sticky enough to roll it in a traditional style) and than climbed in the box and stomped down the snow. I continued the procoess of filling it up and stomping it down until I had completely filled it up with compacted snow. Make sure you compact it near the edges otherwise you could end up with a soft spot. I than used a box cutter to cut the box from top to bottom.
