Combine cornstarch and water in a saucepan.

Stir until the mixture is smooth.

Heat over medium heat, stirring constantly.

Continue heating until the mixture thickens and becomes translucent.

Remove from heat and allow to cool to the touch.

Lay large cookie cutters on parchment paper to create a mold.

Dip yarn pieces into the cornstarch glue.

Remove excess glue by running the yarn between your thumb and forefinger.

Lay the glue-covered yarn inside the cookie cutter.

Repeat until you have a thin layer of yarn inside the cutter.

Press the yarn flat with clean hands.

Carefully remove the cookie cutter.

Let the design dry for approximately 24 hours.
