4 Sided Doilies and Circular Patterns
Four sided doily snowflakes seem to be the easiest format of paper snowflake for those beginning at scissorsmithing. These symmetrical snowflake patterns are fun and easy.
The primary shape of most snow crystals is hexagon. Four sided things just don't happen in nature. There are no four-sided animals or birds, no square fruits or vegetables or snowflakes. This might be why the four-leaf clover is celebrated, because it is so rare.
Four sided snowflakes is an entirely human invention. Square doily flakes are popular because of simplicity. Four simple folds and easy for little hands to manipulate the folds and cuts. Once the kids get the hang of the 4 sided introduction patterns they can graduate to the 2, 3 and 6 sided patterns.
