Step 1

Make the Ears

Download our free printable pattern to get started on this DIY mouse costume. Trace the ear pattern onto cardboard twice, and cut out both ears. Using a foam paintbrush and fast-drying acrylic paint, paint the ears gray and let dry. Paint the inner portion of each ear pink and let dry again. Use hot-glue to attach the ears onto a headband; we suggest using a headband your child is used to wearing, to avoid discomfort while trick-or-treating.

Step 2

Make the Tail

Trace the tail pattern onto gray linen fabric and cut out the shape. With the right sides of the fabric together, sew the long edges of the tail together, leaving an opening on the end. Turn tail right side out and use the open end to stuff the tail with polyester fiberfill and stitch the opening closed. Use a safety pin to pin the tail to the child's leggings or sweatpants. 

Beginner's Tip: The right side of the fabric is the side you want to see on the outside of the project. The term "wrong side" refers to the fabric that will be on the inside of the piece.
