"I wanted to share this quick and easy DIY with you guys because I often get asked where I purchase my large white vases from," she captioned her post.

Tiffany typically finds these large vases at op shops like the Salvos store and then gives them a clean before painting the exterior.

"A quick stop into my local op shop and a bit of white paint mixed with baking powder and that's the answer," she said.

Not only is the project one of the most easy DIYs you can do, it was also super cheap at just $30.

Tiffany's post was a hit with her followers who loved the project and thought it turned out beautifully.

"What a glow up babe," one person commented.

"Came up so beautiful. Well done," another posted.

There were also a few questions asking for more details on the upcycle.

"Perfection! Do you use anything abrasive to clean before you paint or do you just give it a wipe down?" one person asked.

Tiffany responded, "No nothing, just a quick wipe over and the baking powder helps the paint stick really well."

Another follower wanted to know why adding baking soda was added to the paint.

"Baking powder gives the paint a nice textured look and helps it stick better," Tiffany said.

The baking soda and paint technique is also used by DIYer Geneva Vanderzeil, who refers to it as #trashtoterracotta.

Mixing paint and baking soda together to create a clay-like texture means you can transform any vase or pot to look like a clay piece.

But if you're not keen on the more rustic look, you can just use paint as is on your op shop finds. However, depending on the surface you might need to add a primer first or sue a few coats to get full coverage.
