I have created many little spaces throughout my home and in my yard that I refer to as a sacred space, or a comfy, peaceful space. I'm not an expert whatsover when it comes to placing crystals, furniture, plants, and so on. I truly follow my intuition and I work with what I have. My spaces are constantly changing as well. As long as you love your space, go for it! To dive deeper, I recommend researching feng shui and bagua map.
