You’ll need some coasters not to spoil your furniture with hot tea or hot coffee mugs. Here’s an easy way to make some cool coasters. You’ll need 1 piece of self-adhesive shelf liner or contact paper, 1 set of 4 circle-shaped cork coasters, a circle cutter, a ruler, a self-healing mat. Measure the area you wish to cover with shelf liner and locate the circle size; hole on your circle cutter. Insert the cutting tool into the appropriate hole. Hold the circle cutter in place. Push the cutting tool down and in a circle shape; peel it off and press the shelf liner onto the coaster. Press it down firmly, rubbing as you go to make sure there are no bubbles. Make the same actions with all the coasters and enjoy your hot drinks without any harm to your furniture.
