Thank you so much. The igloos themselves are made by covering Balloons in snow, letting it set and then removing the balloon. There is a team who do that on the project. My work is luckily to just work with my friend to make all the artwork.
It surprises me still how strong the snow is when you make the structure like domes. Although there is some shrinking over the season they can last until the spring.
To be honest we make up most of the designs as we go along and for me that is what makes it so fun to do. Thanks for the comment.
