Begin by drawing simple star shapes on the sponge with a marker. You’ll want two stars of different sizes, which you should be able to get out of one sponge.

Cut out the stars.

Spread yellow and white paint on a flat surface. A paper plate works, or just a flat scrap piece of cardstock.

Dip a sponge in the yellow paint. Make sure all the tips of the sponge are covered completely with paint. Stamp the sponge on black cardstock. Carefully remove the stamp.

Keep stamping across the page.

Then, do the same with the other sponge and white paint.

Finally, load a paintbrush with yellow paint.

Use another paintbrush to tap on the handle of the brush, splattering paint across the stars like an explosion of twinkling lights in the sky.
