Creating a crochet rainbow jellyfish can be a fun and whimsical project! Here’s a basic pattern and description to help you get started:

Crochet Rainbow Jellyfish Pattern


  • Worsted weight yarn in rainbow colors (red, orange, yellow, green, blue, indigo, violet)
  • Crochet hook (size appropriate for your yarn)
  • Safety eyes or yarn for creating eyes
  • Fiberfill stuffing
  • Yarn needle
  • Scissors


  • Ch: Chain
  • Sc: Single crochet
  • Inc: Increase (2 single crochets in the same stitch)
  • Dec: Decrease (single crochet 2 stitches together)


Jellyfish Body:

  1. Start with the color of your choice, preferably the base color for the jellyfish. Make a magic ring (adjustable loop) or ch 2 and work into the first ch to form a ring.
  2. Round 1: Sc 6 into the magic ring. Pull tight to close the ring. (6 stitches)
  3. Round 2: Inc in each stitch around. (12 stitches)
  4. Round 3: Sc 1, inc around. (18 stitches)
  5. Rounds 4-8: Sc in each stitch around. Change colors to create rainbow stripes as desired. You can choose to alternate colors or create specific patterns.


  1. Cut strands of yarn in varying lengths (about 12-18 inches) in rainbow colors.
  2. Attach strands to the bottom of the jellyfish body by folding them in half and pulling the folded end through a stitch on the bottom edge. Pull the loose ends of the strands through the folded loop to secure.
  3. Repeat this process, evenly spacing the strands around the bottom edge of the jellyfish. You can attach as many strands as you like for the tentacles.


  1. Attach safety eyes or embroider eyes using black yarn or embroidery floss.
  2. Stuff the jellyfish body with fiberfill stuffing until it’s your desired level of fullness.
  3. Close the opening at the top of the jellyfish by continuing to crochet rounds of sc stitches and decreasing as needed to cinch the top closed.
  4. Fasten off and weave in any loose ends using a yarn needle.

Your crochet rainbow jellyfish is now complete! You can adjust the size, colors, and details according to your preferences. Remember, crochet patterns can be quite flexible, so feel free to get creative with your design. Happy crocheting!
