I just couldn’t quite get my act together early enough this year. And, let’s be honest, with a 5 month old, the only reason he was truly getting dressed up for Halloween was for mom to take a commemorative photo. That being said, this “super” mom pulled together a little something the day before that was quick, cheap and inspired by a children’s book (which counts for extra points, right?)



Optional: Shirt or Onesie

1 8 x 12 piece of gray felt

1 8 x 12 piece of pink felt


1 8 1/2 x 11 piece of light brown cardstock

1 8 1/2 x 11 piece of dark brown cardstock

If You Give a Mouse a Cookie Costume

Putting it together:

Outfit: I started out by perusing our little man’s closet for an outfit we could pull off that we had on hand. While the color of the overalls may have not been perfect, they were free.
Ears: I cut roughly a 1-inch-wide strip of the gray felt and sized it to our “mouse’s” head. Then, I used a dot of hot glue to hold it together.Next, I cut each ear piece (no stencil, just eyeballed it) and hot glued them to the headband.
Cookie: I cut out a large circle from the light brown cardstock and punched two holes at the top. Then, I cut out several “chocolate chips” from our dark brown cardstock. Finally, I added a piece of twine to tie this delicious paper goodie around little man’s neck.
This whole costume cost under $5, took less than 20 minutes to throw together and took all of 3 minutes for our guy to be completely done with.
Happy Halloween 2016!
