The first is the Unique Snowflake and the second is the Cloverleaf Snowflake both from Tatted Snowflakes by Vida Sunderman.
The others are Jon Yusoff's dragonfly pattern-the first is done in Lizbeth Caribbean size 20 with tiny purple beads, and the second is white size 10 with orange beads. The dragonfly twins are going to fulfill a request from my daughter for earrings(they are only as big as my thumb).
