Having spent a small fortune on a retro coffee table, it is a good idea to protect its surfaces with some equally retro coasters such as these Tumbled Tile Coasters from Target.
Sold as a set of four, the coasters are made of stone, which has been painted with different retro patterns. Each tile has a different design, but uses the same colours so they still work well together. One has stripes, two have florals and the other combines flowers with spots.
They cost $14.99 per set from Target.
