This snowflake is worked in one round with just shuttle and ball CTM.
The small 6 point snowflake shapes at the end of each point are given more definition by a double core center ring with rings thrown off.
This snowflake is tatted with Anchor size 40 thread, and is a nice size at about 5 inch diameter. It could be tatted as either 8 or 6 points depending on two small stitch count adjustments.
