My alter is my work space. My room that contains the flaws of my many organization skills. This room should not be entered unless someone announces their presence (excluding the cat, he does what ever he damn well pleases, which includes walking all over the alter)
My many decks use to clutter my alter, but now my laptop dominates its surface. (a christmas gift)
My alter is where I can think and be alone. People know this, and they stay away when I attend my alter, (even the cat stays away at this point).
My alter is my desk, it is always decorated to inspire, refresh, and ground myself.
