TIPS TO CREATE THE LOOK
Use earthen pottery, clay figurines, handcrafted metal pieces and hand dyed fabrics to add small hints.
Create de-cluttered zones. For instance, use only as many table lamps that are necessary for sufficient lighting or only a few cushions on couches.
Keep it minimalistic to accentuate the space which represents the nature of universe.
Leave the ceiling exposed. It will look more authentic.
Use aged raw wood pieces in your furniture like dining table tops or newspaper baskets to make it a piece of art.
