Introduction: Paper Craft Tutorial for Velella Larva

About: Cheryl Teo is a visual artist and craft-based designer who works with paper and other tactile media. She began experimenting with paper in 2011 and turned to building 3D pieces in 2016. Cheryl is drawn to the …

Velella are close cousins of jellyfish. They are a hydroid colony, meaning they have separate sexes. Each colony is considered all male or all female. In its adult form, these little sea sailors have a sail that catches the breeze and are commonly seen floating adrift at sea.

*Although the floating colony stage is the one most people are more familiar with, however this is just one of many stages in a complex life cycle. The colony will later release tiny medusa (a few mm long) which are the sexual reproducing stage and will release eggs and sperm into the water. The eggs can develop into tiny larvae which later develop into the floating colony again!*

The following instructions will teach you how to make your own velella larva using paper. If you're interested in making an adult velella, check out the link here.

Step 1: Materials & Tools


  • Clear coloured vellum paper (160 to 180gsm)


  • Scissors
  • Craft knife for scoring
  • Fast drying adhesive
  • Toothpicks to apply glue
  • Yellow paint ink marker
  • Ruler
  • Cutting mat

Step 2: Print and Cut Templates

Print out the template in the attached PDF. There are two parts - one bigger than the other. Cut out the solid lines only. You can use either a scissors or craft knife to cut. The dotted lines are meant for scoring.

Step 3: Score the Dotted Lines

Score all the dotted lines using the back of your craft knife. Hold your ruler firmly in place with one hand and run the blunt side of your craft knife along the dotted lines, drag it down gently and create a crease. It is necessary to score your lines before folding them.

Step 4: Start Gluing

Start gluing the top part of the larvae together first. Use a toothpick to spread out the glue onto the tabs.

Step 5:

Next, apply glue to the tabs on the side of the larvae template.

Step 6:

Glue the hexagon template onto the top of the larvae.

Step 7: Add Little Yellow Dots

Use a yellow coloured ink marker and apply dots in clusters around the larvae. Repeat the same steps for the other larvae template.

Step 8: Put the Small Template Inside the Big One

Apply glue to the top of the smaller sized template and insert it into the bigger template.

Step 9: Congratulations! You Made Your First Tiny Larvae!
