Make Your Own: Castle Crashers Bitey Bat Mask

Our final DIY mask design is perfect for showing off those fangs — but from behind the barrier of a face mask! Behold: the Bitey Bat Mask!

Trace pattern below, gather your materials, and follow the instructions to make your own batty face covering.


– Black or dark t-shirt/fabric for main mask and wings
– Reddish t-shirt/fabric for Bitey Bat mouth
– White t-shirt/fabric for teeth
– Needle and thread
– Pins
– Paper pattern (Get that below!)
– Pencil or pen to trace the pattern

This pattern uses a scale of 2 inches for an adult medium mask, but you can adjust the size as needed.

Zoom in on the pattern on your computer monitor so that the reference line on the pattern measures 2 inches long. Then, put a piece of paper on the monitor and trace the pattern. Be sure not to press too hard and damage the screen! I also recommend you to write which side is up on the pattern for easy reference.

Note: I left the edges of the fabric untreated for this DIY because I wanted to keep this simple, and t-shirt fabrics don’t fray that easily. If you want a cleaner look, you can fold the fabric and sew over it or use a zig-zag stitch. (If you’re folding the fabric in, you’ll need to add extra ¼ all around each piece except for the main mask pattern.)

PS: *right side = The right side will be on the outside of your finished project.

Let’s get you ready for chompin’!

1. Trace the main mask pattern onto a solid colored t-shirt and cut out two pieces. (Ignore the grey! Use black or a dark color for Bitey Bat… unless, of course, you want a grey Bitey Bat. That’s cool too!)

2. Cut the pieces of reddish fabric for the mouth and put them on the *right sides of the fabric lining up with the Bitey Bat pattern. Pin and sew!

3. Cut pieces of white fabric for the fangs (as sharp as you want!), then pin and sew them onto the red mouth.

4. Put the *right sides together and sew them ¼ inch away from the edge, leaving an opening on one side.

5. Open the pieces up and put them together like the picture below, then sew top and bottom. Make sure to leave ½ – ¾ inch openings on top and bottom of each side for ear loops.

6. Snip around the curve but don’t cut too deep! You don’t want to slice the seam you made.

7. Turn it inside out by pulling the fabric from the opening you made in step 4.

(Although this isn’t a picture of the Bitey Bat mask, you should get the idea. You’re smart!)

8. Cut a ½ inch strip from one of your t-shirts lengthwise, hold both ends, and stretch it out to make it into a string. Most t-shirts are designed to stretch lengthwise without fraying, so go ahead and give it a nice pull.

(The top piece is what it should look like after it’s stretched, while the bottom piece is before.)

Don’t put the string in yet! We’re going to add the wings first.

8. Cut 4 pieces of black fabric for wings. Sew two pieces together but leave the root of the wings open and turn them inside out.

9. Pin and sew a wing to the side of the mask. Make sure that you leave enough room for the string to slip in!

10. Fold the same wing to the other side and sew it on for extra security.

11. Pull the string through using a bodkin or safety pin and adjust the loops to adjust to fit you. Cut the excess string to size and rotate the loop until the knot is hidden inside the mask.

And you’re done! This mask is great because you can look like you’re screaming at people even while your real mouth is hidden inside. NICE!
