Clean the vase and allow to dry.

Using your sanding sponge or sandpaper lightly sand the glass vase to rough up the surface.

Mix your paint and baking soda. The ratio of paint to baking soda should be approximately 3 to 1.

Using an old paint brush, apply the paint and baking soda mixture to the sanded glass vase. Allow to dry and apply a second coat.

Before the second coat dries, use a natural sea sponge to add additional texture to the paint. Do this by wetting your sea sponge and wringing out the excess water. Then gently pounce the sponge onto the wet paint and baking soda mixture.

Optional - go over the texture with your paint brush.

Allow to dry completely.

After the baking soda and paint mixture is dry, smear damp coffee grounds all over the vase. This will give it an aged look.

Allow the coffee grounds to dry completely and then dust them off of the vase. This is a messy process so make sure your work surface is covered or do this step outside or over the trash can.

After the vase has dried completely, apply a clear coat for protection.
