Duodecimal Snowflake Crystal Stencils
Possible appliations for stencil patterns: in addition to place mats and table settings, stencils are handy for scroll saw wooden ornaments, foam ornaments, crochet, embroidery, latch hook rugs and other snow flake needlework projects.
These twelve sided snow flake color book patterns are derived from the snowflakes listed in the fold and cut section of the navigation menu.
Scissorcraft members may view these examples of twelve sided patterns. Look closely to see that the pattern is doubled on both top and bottom so the result will be twelve separate points to the finished snowflake.
Once you get the hang of these designs try your skills with a twelve sided pattern of your own using the blank six sided pattern as a guide. Mix and match with other pattern sizes and types to create a virtual blizzard of paper snowflakes to brighten up the festivities over the cold winter months.
Refer to the six sided pattern instructions to cut out these particular pattern designs. For intricate patterns use small cuticle scissors.
Twelve sided dodecagon ice crystals appear in a 12-sided two-dimensional polygon shape. A regular dodecagon has 12 sides that are all the exact same length and internal angles that are 150 degrees each.
How do 12-sided snowflakes form? Dodecagon shaped, or twelve sided snow crystals occasionally develop in nature or in the laboratory. 12-Sided snowflakes begin when capped 6-sided ice crystal columns twist 30-degrees. Each end-plate begins as a hexagonal six-branched crystal, but when one cap rotates 30 degrees opposite to the other they form a crystal twinning. These two attached 6-branch crystals continue to grow or expand while joined together to form the 12 branch shape. The Science of snow and ice crystal formation.
