Quick Overview

Skill level: Beginner
Construction: One red circle folded into a half slice, then edged in white and green.
Time: About 60–75 minutes total
Finished size: Approx. 2.5 in wide x 1.5 in tall x 0.6 in thick (6.3 x 3.8 x 1.5 cm)
Terminology: US crochet terms throughout
Gauge: Not critical for this small amigurumi; however, aim for a firm fabric with no stuffing peeking through. Because amigurumi looks best when tight, reducethe hook size if you see holes.

Materials

DK/Light worsted weight cotton yarn (Category 3), approximately:
- Red: 8 g (about 18–20 m / 20–22 yd)
- White: 2 g (about 4–5 m / 4–5 yd)
- Green: 3 g (about 6–7 m / 6–7 yd)
- Optional: A strand of black cotton or embroidery floss for seeds (about 30–40 cm / 12–16 in)
Crochet hook: 3.25 mm (D-3). Alternatively, use 3.0 mm if your stitches are naturally loose.
Keychain hardware:
- 25 mm split ring
- 30–35 mm keychain chain
- 8 mm jump ring or small lobster clasp
Tapestry needle: Size 16–18 for sewing and weaving ends
Stitch marker: 1 locking marker (or a scrap of yarn)
Polyester fiberfill: About 3–5 g (a small pinch)
Scissors
Optional: Small pliers for jump rings

Because readers often ask, cotton yarn keeps its shape well and resists pilling, so it’s a great choice for keychains that get daily wear.

Abbreviations (US Terms)

MR: Magic ring
ch: chain
sl st: slip stitch
sc: single crochet
inc: increase (2 sc in the same stitch)
dec: decrease (sc2tog)
FLO/BLO: front/back loop only (not required in the base version)
st(s): stitch(es)
rep: repeat
RS/WS: right side/wrong side (not critical here)

Because you’re working in a small circle, increases are simple and rhythmic. Therefore, keep a stitch marker in the first stitch of each round so you don’t lose your place.

Pattern Notes

This slice is made by crocheting one red circle, embroidering seeds, folding the circle into a half-moon, and seaming the curved edge with white and green to create the rind.
Because we want a clean rind, we add white first, then green as a second round for that crisp watermelon look.
Additionally, lightly stuffing before the last few white stitches keeps the shape plump but not overfilled.
For a tidy edge, consider finishing the green with a reverse single crochet (crab stitch). However, regular sc works perfectly if you prefer simplicity.

Time Breakdown

Red circle: 12–15 minutes
Seed embroidery: 5–7 minutes
Hanging loop: 3–4 minutes
White seam and partial join: 10–12 minutes
Stuffing: 2–3 minutes
Green rind edging: 8–10 minutes
Hardware attachment and finish: 3–5 minutes
Tidy ends: 2–3 minutes

Total: Approximately 60–75 minutes, depending on your pace.

Step-by-Step Instructions

Because clarity helps beginners most, each step includes counts, transitions, and time estimates.

Step 1: Crochet the Red Circle (12–15 minutes)

R1: MR, 6 sc into ring (6). Pull the ring tight.
R2: Inc in each st around (12).
R3: (Sc 1, inc) rep 6 times (18).
R4: (Sc 2, inc) rep 6 times (24).
R5: (Sc 3, inc) rep 6 times (30).
R6: (Optional for a slightly larger slice) (Sc 4, inc) rep 6 times (36).

Because DK cotton and a 3.25 mm hook yield a firm fabric, 5 rounds create a circle about 2.25–2.5 in in diameter. However, if your stitches are tight or you prefer a larger slice, add Round 6. Mark the start of each round and count often. Consequently, your edge will remain smooth and even.

Fasten off red and weave in the tail on the WS. Alternatively, leave a short tail if you prefer to use it later for seed embroidery; however, black thread looks more realistic.

Step 2: Embroider the Seeds (5–7 minutes)

Because embroidery is easiest while the circle is flat, add seeds now.

Thread a tapestry needle with black yarn or floss (about 30–40 cm).
Place 5–7 tiny teardrop seeds on one half of the circle, spacing them evenly and pointing toward the center. Therefore, when you fold, seeds will sit on the visible face of your slice.
Each seed: Make a short vertical stitch (about 3–4 mm), then add a tiny diagonal stitch at the top to create a teardrop shape. Alternatively, small straight stitches look cute too.

Knot securely on the WS and weave in ends. Because the circle will be folded, the ends will hide inside.

Tip: If you want seeds on both sides, embroider the second half as well. However, one side is faster and still looks charming.

Step 3: Add the Hanging Loop (3–4 minutes)

Because attaching hardware is easiest before closing, create a small loop at the straight top edge.

Fold the circle gently in half to find the center of the straight edge (the fold line).
Unfold, insert the hook in that center stitch on the RS, and join the red yarn.
Ch 6, then sl st into the same stitch to form a small loop. Fasten off.

Alternatively, ch 8 for a larger loop if your split ring is thick. Consequently, you’ll have an easy spot to clip the ring without tugging on the fabric later.

Step 4: Fold and Seam with the White Stripe (10–12 minutes)

Because the white stripe represents the watermelon pith, it goes between red and green.

Fold the circle exactly in half with seeds facing outward on one side.
Join white yarn at one corner of the curved edge through both layers.
Working through both layers only along the curved edge, sc evenly across the fold. You will make approximately 15–18 sc, depending on your circle size. Insert your hook through the outer loops of both layers to keep the seam neat.

Count as you go. Because we’re closing the curve, stop 4–5 stitches before the end to leave a small gap for stuffing (see next step). Therefore, you won’t need to force stuffing through tight stitches.

Do not fasten off yet; you’ll finish the last few white stitches after stuffing.

Step 5: Lightly Stuff (2–3 minutes)

Because keychains should be small and plump, add only a pinch of fiberfill.

Insert a small amount of stuffing into the opening. Distribute it evenly toward the curved edge and corners, avoiding lumps.
Add just enough to give shape and body. Consequently, your slice will feel firm but not rigid.

Finish the final 4–5 white stitches through both layers to close the opening. Fasten off and weave the white tail to the inside.

Step 6: Add the Green Rind Edge (8–10 minutes)

Because the rind makes the slice pop, a neat green edge matters.

Join green yarn at either end of the curved edge, inserting your hook under the top of each white sc.
Round the curve with 1 sc into each white sc (approximately 15–18 sc), keeping your tension even.
Optional finishing: Work one more round in reverse single crochet (crab stitch) around the same curve to create a rope-like, tidy edge.

Fasten off and weave in the green tail between layers. Consequently, no ends will be visible.

Step 7: Attach Keychain Hardware (3–5 minutes)

Because you made a loop earlier, the attachment is quick.

Open the 8 mm jump ring with pliers.
Slide the jump ring through the red chain loop.
Add the 30–35 mm chain and the 25 mm split ring, then close the jump ring securely.

Alternatively, clip a small lobster clasp directly to the loop. Therefore, you can swap the slice between bags and zippers easily.

Step 8: Tidy Ends and Shape (2–3 minutes)

Because thoughtful finishing elevates handmade pieces, take a moment to refine.

Check for any tails and weave them between layers.
Pinch the corners gently to sharpen the half-moon shape.
Roll the green edge between your fingers to relax any kinks.

Finally, give your keychain a happy shake. Consequently, you’ll see the seeds and rind sit just right.

Basic Tips for Beginners

Keep tension snug. Because amigurumi should hide stuffing, a smaller hook and steady tension help prevent gaps.
Count often. Since circles grow quickly, it’s easy to add or skip a stitch. Therefore, use a locking stitch marker to mark round starts.
Place seeds before closing. Consequently, embroidery feels easier and looks neater.
Stuff lightly. Because this is a keychain, too much stuffing will distort the edge and push through stitches.
Use cotton for durability. Additionally, cotton resists fuzz and looks crisp on small projects.

Common Mistakes and Easy Fixes

Uneven circle edges:
- Cause: Missed or extra increases.
- Fix: Recount the round you’re on. If needed, frog a few stitches and rework the repeat. Because symmetry matters, (sc 3, inc) repeats must total six times in Round 5.
Seeds bunching or shifting:
- Cause: Pulling embroidery stitches too tight.
- Fix: Ease the tension slightly and anchor tails on the WS. Additionally, space seeds with a finger’s width apart for balance.
White seam too tight:
- Cause: Stitches made through only one layer or with tight tension.
- Fix: Insert the hook through both layers consistently and relax your grip. Consequently, the edge will flex and curve evenly.
Overstuffed slice:
- Cause: Too much fiberfill near the center.
- Fix: Remove a pinch and redistribute. Because it’s a small piece, less is more.
Keyring pulls out:
- Cause: Loop too small or yarn too slippery.
- Fix: Make a heavier loop (ch 8) or double-strand the loop with two threads of red. Therefore, your hardware stays secure.

Variations You’ll Love

Mini seedless slice:
- Skip embroidery. Because the rind and red already read as watermelon, it’s super-fast and modern.
Glitter rind:
- Hold a strand of green with a fine metallic thread. Consequently, you’ll get a subtle shimmer without bulk.
Pastel “candy melon”:
- Swap red for soft pink and green for mint. Additionally, use white seeds for a dreamy palette.
Larger wedge:
- Use worsted weight (Category 4) and a 3.75–4.0 mm hook. Add Round 6 to 36 sts before folding. Because the piece grows in scale, adjust stuffing lightly.
Two-sided seed detail:
- Embroider both halves before folding. Therefore, the slice looks finished from any angle.
Flat applique version (no stuffing):
- Make the red circle, fold, and steam block flat. Whipstitch the curved edge with white, then surface crochet green along the seam. Consequently, you’ll have a slim charm perfect for cards or scrapbook projects.
Semicircle panels method (alternative construction):
- Piece A (red): Ch 2. Row 1: 2 sc in 2nd ch from hook (2). Row 2: ch 1, turn, inc in each st (4). Row 3: ch 1, turn, (sc, inc) across (6). Row 4: ch 1, turn, (sc 2, inc) across (8). Continue increasing 2 sts per row until the straight edge measures about 2.5 in. Fasten off.
- Make 2 panels, embroider seeds on one or both, whipstitch the straight edge closed, then add white and green along the curved side through both layers. Because rows are visible, this version has a cute striped texture.

Care and Durability

Spot clean with mild soap and cool water.
Press gently with a towel and air dry. Because hardware can rust, avoid soaking.
If your keyring snags, trim any fuzz with sharp scissors. Additionally, cotton won’t felt, so it stays crisp.

Frequently Asked Questions

How many slices can I make from one 50 g ball?
- Approximately 5–6 red circles, with leftover white and green for many more rinds. Consequently, a small yarn bundle stretches far.
Can I use acrylic?
- Yes. However, cotton holds shape better and resists pilling on bags and keys.
Do I need safety eyes?
- Not for this pattern. Because seeds are embroidered, there are no hard parts, which makes it baby-friendly as decor. Nevertheless, keychains are not toys.
Can I turn this into a bag charm set?
- Absolutely. Make three slices in different colors, attach them to one split ring with varying chain lengths, and stagger them. Additionally, add a tassel for texture.

Troubleshooting Stitch Counts (Round Reference)

If using the 5-round circle, expect 30 stitches around before folding.
If using the 6-round circle, expect 36 stitches around before folding.
When seaming with white along the curve, you’ll work approximately half that count (15–18 sc) through both layers. Because stitch height varies, the exact number can shift by one or two. Therefore, prioritize an even, unruffled curve over strict counting.

Blocking and Shaping (Optional but Helpful)

Light steam before folding can relax fibers. However, keep steam away from acrylic and hardware.
After finishing, pinch the corners and smooth the rind with your thumb. Consequently, your slice will look tidy and photo-ready.

Make It a Gift

Because small handmade gifts feel extra special, pop the finished slice into a tiny glassine bag or tie it to a card with baker’s twine. Additionally, pair it with a summery lip balm or a mini hand sanitizer for a cute keyring set. For nursery decor, stitch several together, string them on cotton cord, and create a fruity garland.

Recap and Next Steps
