You may have seen witches signing off with the signature line "FFF" or "FFFF" and wondered what these letters stand for. In some online witchcraft communities the series of F's is used much like Wiccans use "BB" for "Blessed Be". Indeed, FFFF is also a kind of blessing, although it has very old roots.
The F rune, fehu, is a mark of prosperity and good fortune. It, in and of itself, is a blessing. When tripled or quadrupled its energies are increased exponentially. FFFF is, quite literally, a spell. FFFF stands for "Flags, Flax, Fodder and Frigg";
Flags = the flagstone, the home, the hearth and the hearthfire Flax = clothing, the material of weaving, the benediction of the weaver's power Fodder = food for animals and people Frigg = the Goddess Frigg, also slang for copulation
So, Flags, Flax, Fodder and Frigg can be translated as "Blessings of the hearth, the weavers, abundant food, and love/sex/fertility".
