Here is a picture of my altar set up for everyday use.
The double cubical altar is good for limited space. It is tall enough to be easily reached while standing. Though, back in America, I had a round table and on top, I put a cable spool of the same diameter, covered in vinyl. This made it the right height and gave me a shelf under it. I miss the round altar.
I keep it in the South so it it out of the way, and the window next to it allows me to see the moonlight reflecting off the Adriatic Sea. I sometimes move it to the centre of the room so I can walk around it. As you look at it, you are in the North, looking South.
In the East, I have a slab of amethyst. On it, I have a paper pentacle, and on top of that, I have a 360° protractor with a skull on it that I got at the Krapina Neanderthal Museum. It and the plastic skull are because we are approaching Samhain. Also on the Slab is a highly charged crystal, and an uglier one that came to me in one of my early outdoor rituals 30 years ago. (my tradition does Earth in the East)
In the South, I have a long lighter (my tradition forbids matches in circle) which makes it easier to light candles in deep holders without burning myself. Also I have an Athame.
In the West, I have a chalice. It's freshly polished, but it's silver-plated brass and I have polished much of the silver off. Also I have a small blue bowl. When I am using the consecration that is in the app, I put salt in it and move it to the East side of the altar, on the slab. I return it to the West, After I have dumped the salt in the Water.
In the North I have a chime with a clapper. I used to use a clapperless bell that I would ring with my Athame. But I like the sound of the chime more because if I cam careful it rings for a really long time. Also a have a censor with a stick of incense. (I only use the thurable for special occasions as I have touring the charcoal from America) And my Wand is the in the North. Also there is the Tarot card I am studying today, in two different decks.
In the Center are my Deity statues. The Goddess statue is also a tea candle holder that shines light on the god statue, which is from cycladic period Greece.
I also have a large plant next to my altar and smaller ones are still out on the balcony. (not cold enough to bring them in yet)
