  5. Paint a cat face using face paint.

Sam I am costume

Supplies

  • Yellow onesie or oversized long-sleeved yellow shirt and sweatpants or old costume with a similar look
  • Red top hat
  • Large platter
  • Green fabric
  • Scissors
  • Velcro or sewing needle with thread
  • Toy ham and eggs (use old toys from a kitchen play food set, pretend play eggs (such as plastic Easter eggs) paired with a ham dog toy from your local pet store, or make them yourself)
  • Glue
  • Slippers
  • Yellow fabric or yellow spray paint

Instructions

  1. Gather the items you are using for ham and eggs.
    • If you need to make a ham, cover a kitchen funnel with light green fabric and use a black permanent marker to create the bone.
    • If you need to make the eggs, you can use light green felt ovals for the whites and dark green felt circles for the yolks.
  2. Trace a rough outline of the toy ham and eggs on the green fabric large enough to cover the toys.
  3. Cut out the fabric. Either sew the fabric around the toys or use Velcro to close the fabric around the ham and eggs.
  4. Glue the ham and eggs onto an old platter.
  5. If your slippers are not yellow, you'll need to cover the tops in yellow fabric or spray paint them yellow to match the rest of your costume.
  6. Put on the yellow shirt and pants or old costume. Remove any old identifying marks.
  7. Add yellow pants, if needed.
  8. Add a red top hat.
  9. Carry the platter with you so people recognize your character right away.
