Crystals (Rose quartz, amethyst, citrine, black obsidian) in a number of different places. I regularly smudge my home with white sage. I have neutral tones with a pop of colour (sage green). Very calming.
My favorite color is green and i love natural and earthy things/colors… so i surround myself with those for a grounded and peaceful vibe. in the evening, my room is lit by a salt lamp and candles for further relaxation. also, snuggling in bed with my dogs adds to the coziness!
