If you like to keep feathers on an altar, but are annoyed at how easily they move around and fall off (bc theyre so light), or if a pet keeps knocking them off and playing with them, you can get a small vase to keep them in
These are my elemental forms with 1st, 2nd, and 3rd tiers for my series. For example of 3 tiers, in the air, fire, water, and earth has 3 tiers each in four.
Dumb rant about art incoming. Something about the character design of Pixar's Elemental disgusts me. It's not just the generic belongs-in-a-heartburn-ad look of the female lead or the Generic Pixar Man (water edition) look of the male lead. It's the fact that the earth and air elementals, almost all of whom are background characters, are stout and large and round, while the protagonists (and certain water and fire side characters) still follow the obnoxious Pixar "slimthick woman, slightly out-of-shape (but not fat!!) man" rule of character design. And they're all just so, so boring. Look at this and try to feel anything.
An obvious option to represent the element of air that I rarely ever see mentioned: Fans. A ceiling fan on your room, or a small electric fan that could sit in a purse, or a hand fan (you can make your own with paper), or a fan you keep on your desk, or a box fan in the window, or a standing fan upstairs, etc.
