The second step is to gather your snow (this is where the shovel and bin come in handy) in a big pile and make your base. I personally like to have a thin layer of snow on the ground in my igloo so i am not sitting on grass. If you are using the snow brick mold you wanna make a circle of how big you want you want the inside of your igloo. After that you wanna start stacking the bricks on each other like how they do on a building. The pattern should be one brick sitting centered on top of two bricks. Ill provide a picture in case you don't get what i am saying. While building up make sure to start shaping the bricks to lean inward to give you the dome look. If you think its becoming unstable get a few sticks to help prop up the walls on the inside so they don't fall. If your not using the snow brick mold you just want to do the same thing as if you were using the snow brick mold. Instead though you just want to pack it together in a circle and as you build up start shaping the wall to lean inward. Trust me on this if you are just going to pack it make sure to have sticks to hold up the walls.
