I know somebody was asking about symbols used. I can't give you the wiccan ones (as I'm not wiccan) but I can give you pagan ones that I use.

The big one for me is the pentagram (5 pointed star within a circle) or pentacle (5 pointed star). The 5 points stand for the 5 elements, spirit, earth, air, water, fire. I use the pents inverted as well as the "right way up". The top point (for me) is spirit, so when I'm using it inverted it means that the earthly elements are paramount in the workings I'm doing.

As for items I use, see below. I don't always use items in ritual, I can pretty much do the whole thing wherever I am. In saying that I do like to have something I can use for the elements, even if it is a cup filled with water, a twig, a rock & a feather and a handful of salt.

Robes - I either do my rituals in a robe or skyclad (naked), you are all equal in front of the gods if you're all dressed the same (or naked). There is also a whole ritual aspect to getting ready for a ritual, dressing etc.

Athame - a blunted knife, associated with fire & the male aspect. I use my athame to mark out the circle, to cut a doorway into the circle if needed (like if somebody has to leave for a reason). A friend made my athame for me.

Sword - pretty much same as the athame - I've only used swords for a large scale ritual.

Chalice - associated with water & the female aspect. I have a gorgeous silver one that I picked up op shopping years ago.

Cauldron - also associated with water & the female, but can be used for fire. I used to use my cauldron to burn things in - I don't have one any more. So I use a ceramic bowl instead. I think DH is trying to hunt another cauldron down for me.

Wand - associated with air & the male aspect. Mine is very plain - actually it just looks like a branch of a tree (which is what it is).

Besom (broom) - I used to have an "old school" hand-made one until it got used to the point it fell apart. Now I just use my "outside" straw broom.

Censer - insense burner. I have a multitude of these around the house, for oil & for using charcoal blocks on them.

Actually you couldn't really tell in our house where my altars are (there are a few), because they blend in so well with other things. My family altar has pictures of my family, some crystals & rocks & a few small candelabra - so it looks like any other shelf. I have unusual things around the house, like a small vase with some feathers in it, or the candles used by my quarter callers at our wedding, or the candle used by my fire quarter which are used in ritual but don't look out of place.
