Crochet jellyfish projects can be a small keychain, a no sew spiral worked amigurumi, a paired mommy and baby design, or a ten tentacle no sew build. These seven original patterns state their scale, tentacle construction, and material approach.
Fiberfill covers the amigurumi versions here; the no sew tentacle builds skip extra notions almost entirely.

Jellyfish patterns to explore
1. Jellyfish Keychain
Kali’s keychain jellyfish at The Friendly Red Fox is meant to double as a backpack charm. It uses about 20 g of worsted (aran) weight yarn in a main and an accent color, a 3.25 mm hook, and 6 mm safety eyes, with embroidery thread for the mouth. You also need polyfill, a stitch marker and a keychain hardware piece (she links the kind she uses). Because it uses so little yarn, it is a good scrap-yarn project, and the safety eyes mean it should stay a keychain for older kids and adults.

2. No Sew Jellyfish
Fay’s no-sew jellyfish is designed for keychains and bag charms, and the page says it works with any yarn weight and fiber. The teal and pink samples are Paintbox Cotton DK. For a larger, softer version she used Premier Yarns Parfait Chunky, a 4.5 mm hook and 10 mm safety eyes, with a few small adjustments. Since nothing needs sewing, it is a good pattern for market prep, gifts and using up leftover yarn.

3. Mommy and Baby Jellyfish
Sweet Softies pairs a mommy jellyfish with a tiny baby jelly, made in Hobbii Amigo XL yarn in a range of shades. The designer’s safety note is the most useful part: if the toy is for a newborn, infant or young child, skip plastic safety eyes because they are a choking hazard, and embroider the eyes instead. That makes the pair a practical option for a baby gift, and the mini size means it works up quickly.

4. No Sew Jellyfish Amigurumi
Cuddly Stitches Craft’s jellyfish is rated beginner to intermediate and needs only basic stitches. With a 3 mm hook and fine sport (#2, 4 ply) yarn it comes out about 25.5 cm (10 inches) tall and 9 cm (3.5 inches) wide, and the sample uses two YarnArt Jeans colors (50 g, 160 m each). The page lists cotton, acrylic and blend substitutes for both sport and DK weight. Larger yarn will give a bigger jellyfish, so check the finished size if it needs to fit a particular spot.

5. Crochet Amigurumi Jellyfish
Jenny the Jelly by Yarnhild finishes about 13 cm (7 inches) including the tentacles. The designer made one in sport weight and one in worsted weight to show how yarn and matching hook change the size. Beginners should note her recommendation to sew on the eyes rather than use safety eyes when making it for babies. It is a good one to make in several sizes to compare.

6. Julie the Jellyfish
Julie the Jellyfish by The Nicole Chase is 2.5 inches tall for the body and about 8 inches long with the tentacles. It is worked in medium (4) worsted weight yarn (WeCrochet/Knit Picks Brava Worsted in the sample) with a 4 mm (G) hook, and the page states the yardage for each color, so you can use up scraps without guessing. Gauge is not necessary. The page includes a video tutorial, plus stitch markers and a tapestry needle as tools.

7. Mochi the Jellyfish
Holly Lanier’s Mochi is pitched at beginners because the size is not too big and not too small, and there is very little sewing. The sample uses Hobby Lobby I Love This Yarn in Orchid and Menthe with a G (4 mm) hook, 10.5 mm black safety eyes, fiberfill and black embroidery floss, plus a small amount of white and pink for the cheeks. The finished jellyfish is about 5.5 inches, and a full video tutorial is included.
