This is a simple rangoli.
I am a craft maker. Recently doing one wall mural by name Vasthumural. Just I tried the idea with Rangoli in colour. (I don't have any knowledge in Vasthu).
We can even call this kolam as vasthu kolam since Om, swastic, kalsa and Lakshmipathams are in. Inside design can be done freehand or 9 to 1 straight form.
