The first step is to import the shapes you need: a triangle, a rectangle, a star, and a text block. Next, you will create a firework shape, which is a rectangle with a triangle on top. Then, you will combine the shapes.

Now, create an outline of the firework shape. Then, add stars to make it look like a firework. Finally, add the text "Happy 4th of July."

For this, I used an XTool stone coaster because they won't get damaged by water condensation.

Now it's time to use the laser. I have an S1 40-watt laser, so adjust your machine settings accordingly. And don't forget to wear your laser safety glasses.

Now that you have finished making your coaster, you are one step closer to being ready for your party.
