Here’s anothere easy to make costume that can be adapted for warm or cold weather. Make your child or yourslef into an aquarium! Take a rectangle box and paint it blue to make water.
Cut out gold fish from construction paper and glue them all over the box. You can add fishing netting or a gold fish scooper or anything that you might find in a fish tank. Then you have an instant aquarium.
If you don’t want to do the painting you can go to the fabric store and buy blue fabric or underwater fabric with ocean sceans. THis is a project that your child can make him or herself with simple designs or an adult can make as elaborate as you can imagine!
