The first step is to insert stars and rectangles, then adjust their size to your liking to create the firework shapes.

Now you will add your decorations to the fireworks. I used score lines and more stars.

For this, I used basswood and don't recommend using another material. I plan on painting and gluing this project.

For this, you need to color the front and then glue on your twine. Finally, attach the star to the top of the firework twine.

Now you're done with your firework decoration. Good job!
