Yeah, I prefer the less fuss the better. The shapes all have their meaning ... Like a square is material manifestation and anchored in earth, so I use it for my altar. I've used rectangular tables, foot rests, tree stumps, the floor, wall shelf, book shelf, dresser, even the top of a washing machine, ... But all my altar cloths are square, because bandanas are made that way. No special meaning unless I want one.
I don't always cast a full Wiccan circle either. And I've experimented with a few different kinds, and different directions of motion and what not. I like a north-oriented, circular, counter clockwise shuffle step for special space just to meditate. It dissipates when I walk out of it. More often than not, I meditate in my recliner chair, in a NE corner facing SW because that's where it fits, and no circle. I store my stang next to my Lady Shrine, leaning against a north wall. So it's always set up. Eh, too much info.
