You will need:
Plank of wood
Some wood cutting tools -- I used the vertical band saw
A few images with a common theme
Step 1: Create your coasters on Illustrator and laser the images
Design your coasters however you like. Would be good to stick with a theme here.
Download my .ai file in the attached section if you'd like to use it.
For rastering - 75 speed/ 90 power
Step 3: Lastly, sand down the edges
No more cup imprints on your coffee tables!
