Hi all...long time lurker, first time poster etc. This is gonna be long so sorry in advance!
Like many I came to paganism through feminism. I remember getting a detention at school for 'promoting witchcraft' (ironic as I was merely exploring Celtic and Wiccan symbology - fun fact I grew up in the same road as Gerald Gardener but only found out about that last year!) I don't really identify as anything other than Celtic Pagan. I was raised by a Lapsed Catholic and my mother unknowingly had many paganistic things around her house. She collects Green Men! I have always collected crystals and set intentions (as well as many 'superstitious' things like a broom over the door, always having a bay leaf and pentacle in my purse, bowls of sea salt around the house, sageing, growing rosemary by my front door etc.)
With regards to altars, although I don't do much magical work these days I always have a place to pay respect to the elements. Even though I live alone in a 3 bed house I have always felt I wanted this in my bedroom, so I have a small area on the top of my chest of drawers that incorporates the elements. Similarly I always carry (in the small zippy pocket of every handbag!) a feather, a small shell, a pebble and a cinnamon stick to represent the elements. I also have a mint tin containing these and a penny and quartz crystal in the glovebox of my car. They are just small things but I like having them.
I have never felt the need to hide my stuff from my family (bit hard as it's everywhere. I have a huge 'Strega' apothecary cabinet full of tools, books and curios) and I'm lucky as they are open-minded enough to not mind me answering questions when children and teenagers ask me about it. Indeed my sibling's children love crystals and each have their own growing collections! As I just turned 40 (and am childless!) I suspect I'm in Maiden/crone limbo!
I recently gave a friend a book called Pagan Paths that she found very helpful. I got it on amazon. Also an excellent article on dowsing in Fortean Times recently that you can find if you google.
