This lovely snowflake was designed by Lenore English as part of a (sadly unfinished) "year of snowflakes" series. I enjoy the multiple nested shapes, and the clever way she formed the clover/trefoil at the tips of the inner star - one ring is made in the round with the star, and the two on either side are made in the following round, and join at the base of the center ring - a useful technique for beginners who often have a gap at the base of their rings. Note: mine ALWAYS needs to be blocked firmly to lie flat, and looks better when starched and pined firmly to stretch the inner star into pointy elegance.
I don't know if Lenore has a current website - this pattern was posted on Geocities and is available via the wayback machine here. If anyone knows of a current site for Lenore, please let me know!
