Snowflake Ornament as Ringed Argument 

Having constructed a simple stellar dentrite experimentally, its time to turn it into usable blocks. Note that the original (Designing Snowflake Ornament) had some issues: (1) Backtracking was lazy, doubling the amount of satin stitch necessary. To avoid jump stitches on backtracking use a technique called "underlay" from professional machine embroiderers. Also time to parameterize the angle of the snowflake.
