What you need
- A plastic placemat or two (I’ve used Ikea’s one but any other one can do as well)
- Large Mug/Jar/Glass/Round container whose diameter exceeds the diameter of your regular mugs/glasses
- Pencil, pen or marker
Place the Round container on the placemat, draw around it with your pencil and then simply cut it out. And it is as simple as that; one placemat can make 4-6 coasters depending on how large you want them to be.
