I just finished this snowflake. The pattern is from Jane Eborall and you can find it here. It uses Split Rings and Lock Chains (Ric Rac chains). I used white and purple threads (I think both are El Beida) and purple seed beads. This is really a lovely snowflake! Took me around 3 hours to finish, having some mistakes to correct. It has a little "oops" but it's not too noticeable and didn't affect the design.
