It is surprisingly difficult to find snowflakes with hearts in them. This lovely snowflake is Darling Josephine from the book "Tatted Flurries" by Sharon Briggs. My tension wasn't quite right for the pattern as written, so I lengthened the horizontal bar between the hearts with an extra Josephine knot and set of stitches. I have mixed feelings about Josephine knots (the little disks/bobs) - they are cute, but every so often I have one which refuses to close neatly and it's very aggravating! Next time I might use picots instead. ;)
I received this book for Christmas (yay!) and haven't made very many things from it yet, but the snowflakes look very interesting. Patterns are diagrammed, and all the snowflakes in the book are pictured on the front and back covers so you have a good idea what you're getting. It can be purchased directly from Sharon on her website (which also has some free patterns).
