Wiccas, what is the blue star?

No, the Wiccan Rede doesn't say that. The Rede is : An Ye harm none, Do what Ye Wilt. Some will use more common language such as "In it harm none, you what you will."

Your quote " "when misfortune is enow, wear a blue star on your brow." is a line in the poem Rede of the Wiccae, which is a poem written specifically for The New England Coven of Traditionalist Wicca. This poem hold no significance in other traditions.

ETA: According to the Blue Star tradition, a Blue star is a Septagram, aka a faerie or fey star (a seven pointed star)

The Wiccan Rede is only eight words, and no where does it say "when misfortune is enow, wear a blue star on your brow."

You're confusing the Rede with a poem first published in the late '70's in an issue of "The Green Egg". The Wiccan Rede is not the same thing as "Rede of the Wiccae".

As for what it means, that depends on who you ask. I saw once, when you're in trouble, visualize a blue star for protection. Not sure how true it is, many interpret this poem in their own way.

That long poem is not the Wiccan Rede. It was built up around the Wiccan Rede.

The actual Wiccan rede is only 8 words: 'An it harm none, do what ye will."

Personally I think the poem is drivel. I've heard many interpretations of what it might mean, the blue star may be some type of ornament/charm... I don't know for sure myself, we don't use that poem in my trad.

Not Wiccan but found this

These are a few of the interpretations I have found.

1. This is a seven-pointed blue star (or septegram). This symbol is used by the modern Blue Star Wicca tradition. This is a reference to Queen Aster of Phoenecia, who assisted Aset (Isis) when Isis was mourning the death of Asar (Osiris). Queen Aster became a Goddess and a star in the night sky, worshipped throughout the Middle East as Aster, Astarte, and similar names.

2. In this form, it means to open your third eye and listen to your higher self/Spirit Guide/Guardian Angel whenever you find yourself in difficulties. I was taught a slightly different variation: "Wear the blue star on your brow" which harkens back to the days of Welsh villages, and may be evolved from the blue crescent of woad worn on the foreheads of the Picts...

3. When misfortune is enow, wear the blue star on thy brow. It is long believed that the Pentagram is a sign of protection from the mother. Cut an apple through its middle and the seeds will form the star. When you feel as though the world is out to get you and nothing is going right, draw the pentagram on your forehead over your third eye. Make sure you imagine it as a blue flame. This will both protect and cleanse your own personal perspective to help you overcome the misfortune.

What you've quoted as you've already been told is not from the Rede.

There is a Wiccan tradition called the Blue Star tradition. But, I am not a member so, I don't know if your quote is referring to them or not.

That's not from the Wiccan Rede, I've never even seen that before. Not saying it isn't Wiccan, just not from the Rede.

Just sort of a guess, but it makes me think, third eye...probably not it, but like I said, I've never even seen that before.
