Shark Lunch Bag | OLFA - Craft OLFA – Craft

Shark Lunch Bag

Satisfy your kid’s appetite and make lunchtime exciting with this easy-to-make Shark Lunch Bag. All you need are a few rolls of colored duct tape, OLFA rotary cutters and a cutting mat. The bag is way easier to make than the many lunches it will hold this school year.


Durable duct tape is tremendously sturdy and the sheen of the fabric side looks as slick as a real shark’s skin! OLFA rotary cutters and OLFA cutting mats are the absolute essential tools to work with duct tape for this and any other cool project. The long-lasting quality of the duct tape will ensure this shark lunch bag stands the test of a school year while adding a little fun to your kid’s daily routine. Who wouldn’t love stuffing their lunch in a shark?


  • Before you start this project, decide what colors you would like to use for your shark. We chose bright blue for our shark, but your child might prefer purple, black, white or green. It’s fun to personalize. Black and white is the perfect combination for a killer whale. Just some suggestions, but let your kids choose their favorite.
  • Watch our “How to Make a Shark Lunch Bag” video once or twice. We’ll show you the steps and techniques to quickly complete this craft project.




28mm Rotary Cutter (RTY-1/G)
45mm Splash Rotary Cutter (RTY-2C/PR)
18″x24″ Rotary Cutting Mat (RM-SG) 


Duct Tape (blue, black and white, or your choice)
Adhesive hook & loop fastener
5” x 7” piece of thin cardboard


  1. Cover a 5” x 7” piece of thin cardboard (such as cereal-box cardboard) with duct tape. This will be the bottom of the bag, making it nice and firm.
  2. Create duct-tape “fabric sheets” by layering strips of duct tape, adhesive side to adhesive side, in opposite directions. On each side, overlap the long edges of the tape strips, creating one large fabric sheet. Trim the fabric sheet edges with an OLFA 45mm Rotary Cutter to make them straight and clean.


  3. For this project, you will need to make fabric sheets in these dimensions:
    – Make one 12” x 7” back panel. Cut the top 5″ into a curved shape with your rotary cutter to make the outline of the shark’s open mouth.
    – Make an 8” x 7” front panel.
    – Cut two 7” x 5” side panels.


  4. Arrange the panels with the cardboard bottom piece in the center the side panels on the sides and the front and back panels in the appropriate positions (see “How to Make a Shark Lunch Bag” video above). Using the same color duct tape, tape all sides to the cardboard base on both front and backsides to form hinges. Fold panels up and tape the edges of the sides to the front and back panels. Be sure to reinforce by taping both the inside and outside seams.


  5. Add details:
    – Make a smaller duct-tape fabric sheet if you don’t have enough extra material from the fabric sheets above. Using your rotary cutter, cut three small fins. Two fins will go on the front of the bag at the sides and one fin will be taped to the back. Also cut two half circles for eyes.

    – From a single white strip of duct tape, cut two smaller half circles to fill the eyes, and then two smaller half circles from black tape to complete. The adhesive will be exposed, so you can easily stick these pieces in place.

    – On the cutting mat, make a piece of black duct-tape fabric about ¼” to ½” smaller than the mouth on the bag. Cut out two large black half circles for the mouth.
    – Press a strip of white tape on the mat and cut small white triangles for the teeth. Peel and press them in place along the outer edge of the black mouth pieces.


  6. Add adhesive hook & loop strips both at the base of the mouth and the front of the bag in the inside.


  7. Tape eyes to each side of the shark’s head, two fins to each side of the bag’s front, and one fin to the back. Add the black mouth top and bottom (in a mirror image) to the back of the bag. Cut two tiny rectangular strips of black tape for the nose detail.


  8. Fold an 8” piece of duct tape in half lengthwise to form a carrying strap. Tape the strap to the bag at the back, just below the fins.

Great job! Your shark lunch bag is now finished and you’re ready to pack a delicious lunch that both the shark and your child will devour!


  • When creating details like the mouth, eyes and teeth, allow the adhesive part to stick onto your OLFA cutting mat. This makes it easy to peel off the tape shapes and stick directly onto your lunch bag.
  • Double up and layer additional duct tape at the seams for additional strength and durability.
  • Use these instructions as a guide but let creativity take over. Give your shark personality with fewer, bigger, sharper shark teeth or funny eyes using rectangular slits instead of half circles for the centers. How about a pink mouth? The possibilities are limitless.
  • If your project shows wear throughout the school year, reinforce the seams with additional duct tape. Good as new!
