Sigils can be worked in large temporary structures in group workings or by the solitary practitioner. Perhaps you could take inspiration from the Rangoli mandalas created by Hindu women during the festival of Diwali.
I think it’s a beautiful way to give your intent to the wind by working in such a transient media as sand or rice powder.
Ooh that makes me thing sigils in the sand to be washed away by the ocean… So many possibilities…
Do the images of Rangoli inspire you to work a little large scale Sigil magic?
