Start by covering your table with cardboard. Make sure your vase is clean and dry. Now, for the magic of of this project. Grab a palette, plastic lid, or even a piece of cardboard, and squeeze out your selected acrylic paint shades. I went for earthy tones like Burnt Sienna, Yellow Ochre, and Flesh Tint. Add a couple of tablespoons of baking soda on the side. Mix the paint and soda directly with a sponge or brush, but don’t overmix—leave it slightly grainy to mimic the look of terracotta. This texture is key to achieving that authentic, matte ceramic vibe.
