Creating the Body Suit

Start by printing or drawing the Pete the Cat template onto your blue fur fabric. Cut out the body suit pieces, including the front and back of the costume, as well as the arm and leg holes. Sew the pieces together, leaving the arm and leg holes open.

Once the body suit is sewn together, try it on to ensure a comfortable fit. Make any necessary adjustments before moving on to the next step.

Adding the White Underside

Using your template, cut out the white underside pieces from the white felt or fleece. Sew these pieces onto the inside of the blue body suit, making sure they align properly with the arm and leg holes. This will give your costume the signature white belly and inner-leg look of Pete the Cat.

If you prefer not to sew the underside, you can use fabric glue to attach the white pieces to the inside of the body suit. However, keep in mind that sewing will provide a more secure and long-lasting attachment.

Creating the Collar and Ears

Now that the body suit is complete, it's time to add the finishing touches – Pete's red collar and ears!

Making the Collar

Cut out two identical red felt or fabric pieces for the collar, using your template as a guide. Sew the pieces together, leaving one side open to insert the elastic. Add a piece of elastic to the open side, ensuring it's long enough to fit around your neck comfortably. Sew the elastic in place, and you've got Pete's signature red collar!

To attach the collar to your costume, simply sew it onto the neckline of the blue body suit. Alternatively, you can use fabric glue or safety pins for a non-permanent attachment.

Creating the Ears

Using your template, cut out four blue felt or fabric ear pieces – two for the top of the head and two for the sides. Sew each pair together, leaving the bottom open. Once sewn, turn the ears right-side out and stuff them with a lightweight filling, such as polyester fiberfill or cotton balls.

Sew the top ears onto the top of the blue body suit, positioning them just above the eyes. Attach the side ears to the sides of the costume, near the top of the head. You can use fabric glue or safety pins for a non-permanent attachment if desired.

Adding the Final Touches

With the body suit, collar, and ears complete, it's time to add the finishing touches to your Pete the Cat costume!

Creating the Tail

Using your template, cut out a blue felt or fabric tail piece. Sew the tail shut, leaving the top open. Stuff the tail with a lightweight filling, then sew the opening closed. Attach the tail to the back of the blue body suit using fabric glue or safety pins.

For an extra touch, you can add a small white pom-pom to the end of the tail to resemble Pete's fluffy tail tip.

Making the Paws

To create Pete's signature white paws, cut out four white felt or fabric paw pieces – two for the front and two for the back. Sew each pair together, leaving the bottom open. Once sewn, turn the paws right-side out and stuff them with a lightweight filling.

Sew the paws onto the end of each arm and leg of the blue body suit. You can use fabric glue or safety pins for a non-permanent attachment if desired.

Now that your DIY Pete the Cat costume is complete, it's time to show off your feline fabulousness! Strut your stuff at the next party or Halloween event, and don't forget to channel Pete's groovy moves and positive attitude. Who knows? You might just become the life of the party! So go ahead, put on your costume, and let the good times roll – Pete the Cat style!
