There are also instructions in the pattern to make Versions B and C of this snowflake.
Size of finished and blocked snowflake made with suggested thread: approximately 5 3/8” in diameter.

UPDATE: Some of you were not able to view the entire pattern instructions in Internet Explorer (regardless of version). I believe that I remedied this problem, and the instructions should be now visible in their entirety. My apologies for the inconvenience. Thank you to all, who brought this glitch to my attention.
