Materials Needed

Before you begin, gather the following supplies. All items are readily available at craft stores or online, and most are likely already in your stash.

Yarn

• Ocean Blue (Main Color, MC): Worsted weight cotton or acrylic yarn—approximately 50 yards. This forms the jellyfish dome.
• Light Aqua (Contrast Color, CC): Worsted weight cotton or acrylic yarn—approximately 30 yards. This creates the tentacles.
• White Yarn: A small amount (less than 5 yards) for embroidering the eyes.

Tip: Cotton yarn gives a crisper stitch definition, while acrylic offers more squish and is often easier for beginners. Either works beautifully for this project.

Needles and Hooks

• US Size 6 (4.0 mm) Knitting Needles: Straight or circular—whatever you prefer for flat knitting.
• US Size G/6 (4.0 mm) Crochet Hook: Used for creating the optional hanging loop and for finishing details.

Notions

• Yarn Needle: For seaming and weaving in ends.
• Scissors: For cutting yarn and trimming tentacles.
• Stitch Markers: At least one, to mark the center stitch of the dome.
• Steam Iron or Spray Bottle (optional): For blocking the dome to smooth stitches.

Gauge

20 stitches and 28 rows = 4 inches in stockinette stitch. Gauge is not critical for this project, but maintaining consistent tension will help your bookmark look neat and professional.

Step-by-Step Instructions

This pattern is knitted flat in two pieces: the dome and the tentacle strip. Follow the instructions carefully, and you'll have a charming jellyfish bookmark in no time. Let's break it down step by step.

Abbreviations

• CO: Cast on
• K: Knit
• P: Purl
• K2tog: Knit two together (decrease)
• Kfb: Knit front and back (increase)
• St(s): Stitch(es)
• BO: Bind off
• RS: Right side
• WS: Wrong side

Dome (Make 1)

The dome is the jellyfish's body—a rounded, slightly domed shape that resembles a mushroom cap. You'll start with a small cast-on and gradually increase to create width, then decrease symmetrically to form the curve.

Cast On: CO 12 stitches in MC.

Row 1 (RS): Kfb across all stitches—you should now have 24 stitches.

Row 2 (WS): Purl all stitches.

Row 3: Kfb, K10, Kfb, K10, Kfb—27 stitches. Place a stitch marker on the center stitch (the 14th stitch) to help track your increases.

Row 4: Purl all stitches.

Row 5: Kfb, K12, Kfb, K12, Kfb—30 stitches.

Row 6: Purl all stitches.

Row 7: Kfb, K14, Kfb, K14, Kfb—33 stitches.

Row 8: Purl all stitches.

Row 9: Kfb, K16, Kfb, K16, Kfb—36 stitches.

Row 10: Purl all stitches.

Row 11: Kfb, K18, Kfb, K18, Kfb—39 stitches.

Row 12: Purl all stitches.

Row 13: Kfb, K20, Kfb, K20, Kfb—42 stitches.

Row 14: Purl all stitches.

Now you've reached the widest point of the dome. The next few rows are worked even to give the dome a bit of height before you begin decreasing.

Row 15: Knit all stitches.

Row 16: Purl all stitches.

Row 17: Knit all stitches.

Row 18: Purl all stitches.

Now it's time to shape the top of the dome by decreasing. Notice that the decreases mirror the increases—you'll work K2tog at the same positions where you previously did Kfb.

Row 19: K2tog, K18, K2tog, K18, K2tog—39 stitches.

Row 20: Purl all stitches.

Row 21: K2tog, K16, K2tog, K16, K2tog—36 stitches.

Row 22: Purl all stitches.

Row 23: K2tog, K14, K2tog, K14, K2tog—33 stitches.

Row 24: Purl all stitches.

Row 25: K2tog, K12, K2tog, K12, K2tog—30 stitches.

Row 26: Purl all stitches.

Row 27: K2tog, K10, K2tog, K10, K2tog—27 stitches.

Row 28: Purl all stitches.

Row 29: K2tog, K8, K2tog, K8, K2tog—24 stitches.

Row 30: Purl all stitches.

Row 31: K2tog, K6, K2tog, K6, K2tog—21 stitches.

Row 32: Purl all stitches.

Row 33: K2tog, K4, K2tog, K4, K2tog—18 stitches.

Row 34: Purl all stitches.

Row 35: K2tog, K2, K2tog, K2, K2tog—15 stitches.

Row 36: Purl all stitches.

Row 37: K2tog, K1, K2tog, K1, K2tog—12 stitches.

Row 38: Purl all stitches.

Row 39: K2tog across all stitches—6 stitches remain.

Cut the yarn, leaving a 12-inch tail. Thread the tail through a yarn needle, slide it through the remaining 6 stitches, and pull tight to gather the top of the dome. Secure with a knot. This creates the rounded, closed top of the jellyfish.

Tentacle Strip (Make 1)

The tentacle strip is a simple rectangular piece that will be sewn to the bottom of the dome and then cut into individual tentacles. It's worked in stockinette stitch for a smooth, polished look.

Cast On: CO 8 stitches in CC.

Row 1: Knit all stitches.

Row 2: Purl all stitches.

Repeat Rows 1-2 until the strip measures 6 inches from the cast-on edge. This will give you plenty of length for the tentacles to dangle below the book.

Bind Off: BO all stitches loosely. Cut yarn, leaving a 6-inch tail for seaming.

Finishing and Assembly

Now comes the fun part—bringing your jellyfish to life! Follow these steps carefully to assemble your bookmark.

Step 1: Attach the Tentacle Strip to the Dome
With the right side of the dome facing you, use the yarn needle and MC to sew the tentacle strip to the bottom edge of the dome (the cast-on edge). The strip should be centered, with the dome overlapping the top of the strip by about 1/2 inch. Sew securely with a whip stitch or mattress stitch, making sure the seam is neat and invisible from the front.

Step 2: Create the Tentacle Tube
Fold the tentacle strip in half lengthwise, wrong sides together, and sew the side edges closed to create a tube. This will make the tentacles more dimensional and give them a chunky, tactile feel. Use the CC yarn tail you left during bind-off, or thread a new piece of CC yarn through your yarn needle.

Step 3: Cut the Tentacles
Cut the bottom edge of the tube into 8-10 thin strips, each about 1/8 inch wide. Trim them to varying lengths (2-4 inches) for a natural, organic look. Don't worry about being too precise—jellyfish tentacles are naturally irregular! You can also curl the tentacles slightly by wrapping them around a pencil or your finger for a few seconds.

Step 4: Add a Hanging Loop (Optional)
Using the crochet hook, attach a small loop of CC yarn to the top center of the dome. Simply insert the hook through the top of the dome, pull a loop of yarn through, and chain 6-8 stitches. Fasten off and weave in the ends. This loop is perfect for hanging your bookmark on a hook or nail when not in use.

Step 5: Embroider the Eyes
Using white yarn and a yarn needle, embroider two small eyes on the front of the dome. Place them about 1 inch apart and 1/2 inch down from the top. Use a simple satin stitch (a few parallel stitches close together) or a French knot for a cute, expressive look. For a friendlier face, place the eyes slightly closer together; for a more whimsical look, space them wider apart.

Step 6: Weave in All Ends
Thread any remaining yarn tails through a yarn needle and weave them into the inside of the dome or tentacle tube. Trim any excess yarn close to the work, being careful not to cut your stitches.

Step 7: Block the Dome (Optional but Recommended)
Gently steam block the dome to smooth the stitches and give it a professional finish. Hold a steam iron about 1-2 inches above the dome and release steam, or lightly mist with water from a spray bottle and let it air dry. Be careful not to flatten the tentacles—only block the dome itself.

Tips for Success

• Consistent Tension: While gauge isn't critical, keeping your tension even will make the dome look smooth and the tentacle strip uniform. If you tend to knit tightly, consider going up a needle size.
• Use Stitch Markers: The center stitch marker is essential for keeping your increases and decreases aligned. Move it up as you work each row if needed.
• Customize Your Colors: While this pattern calls for ocean blues and aquas, feel free to experiment! A pink jellyfish with lavender tentacles would be adorable, or a purple one with teal accents for a more mystical vibe.
• Make It a Gift: This bookmark is small enough to knit in an evening, making it a perfect last-minute gift. Pair it with a favorite book for a thoughtful, handmade present.
