I was playing a little with the pattern for "Remembrance" by Rebecca Diamond (aka TatMom), though I omitted the beads. To me it looks incredibly lifelike - like an actual snowflake.
I did think that a real snowflake wouldn't have arms longer than the tips so tried
adding a ring - and also changed the little ring stitch count to 5 so I
didn't have to remember to switch between 5 and 4. I think this would be an amazing center for a doily.
Not quite long enough, so tried adding a ring plus the same "mock ring" made from a chain joined to the picot on both ends. The longer tip is better, but I lost the lovely triangle by joining to the top picot; maybe I should have used a SCMR instead. Next time...
They all look nice.
Rebecca has generously shared her pattern here.
