About This Pattern
This one feels like a snack break turned into yarn. Green on the outside, white in the middle, red at the center with little black seeds scattered in — it is playful without trying too hard. I always smile when the rind color shows up on my hook.
Your hands stay busy with single crochet and increases building the rounded shape, then decreases pulling it back in to close. You will attach a fresh color partway through, so keep your yarn needle close for weaving in ends as you go. Nothing fussy, just steady rounds.
Clipped to a keyring or hanging off a backpack zipper, this little wedge catches eyes in a doorway or on a hook by the kitchen sink. It is small enough to tuck in a pocket but bright enough to never get lost in a bag.
- Start with green yarn, chain 13, and work single crochet around the chain, increasing at both ends to build the oval base (Rounds 1-2).
- Still in green, work one round in back loops only and one round through both loops to add height, then fasten off (Rounds 3-4).
- Keep decreasing to 12 stitches, slip stitch to join, and begin stuffing the keychain (Round 13).
- Work one more round of single crochet around all 12 stitches, topping up stuffing as needed (Round 14).
- Close the piece by alternating single crochets and decreases until the opening shuts, then fasten off leaving a long tail.
- Weave the tail through the front loops of the remaining stitches and pull tight to close the hole completely.
- Use black yarn to stitch seeds onto the red part of the watermelon.
- Sew the end tightly and attach a keychain or loop as desired.

Where it goes
- Clip it to a keyring so your house or car keys are easy to spot in a bag.
- Hang it from a backpack zipper for a bit of color on a school or gym bag.
- Attach it to a lanyard as a cheerful accent for work badges or ID cards.
- Give it as a quick handmade add-on paired with a notebook or a small tote.
Color ideas
- Classic watermelon Green yarn forms the base rounds (Rounds 1-4), white yarn forms the next two rounds (Rounds 5-6), red yarn carries the main body through the gradual decreases to the closing, and black yarn seeds are stitched onto the red section once the shaping is complete.
Care
Hand wash in cool water if the yarn gets dirty, since most worsted-weight acrylic or cotton blends hold their shape better without a machine wash cycle.
Lay it flat to dry on a towel rather than hanging it, so the keychain loop does not stretch under the damp weight.
Store it loose in a drawer or basket rather than squeezed in a tight pocket, so the rounded shape and seed placement stay crisp.
Assembly
- Step 1 Sew the end tightly and attach a keychain or loop as desired.
Easy to get wrong
Losing count during decrease rounds
Place a stitch marker before each decrease so you always know where the next one falls. Recount after every decrease round before moving on.
Sloppy color change at the white-to-main transition
Drop the old color to the inside and carry it loosely rather than cutting it right away. Weave in ends only after the piece is fully shaped so tension stays even.
Closing hole left loose or puckered
Weave the tail through the front loops only, then pull slowly and check the gather before fastening off. A quick tug test before you cut keeps the hole fully sealed.
Listener questions
Can I make this without a keychain finding?
You can skip the hardware and just leave a small loop of yarn at the closing instead. It still works as a little ornament to hang or clip with a safety pin.
How do I attach the black seeds?
Use short lengths of black yarn and stitch small straight accents directly onto the red section once the main shaping is done. Scatter them unevenly so they read as natural seed placement.
What stitch does most of the shaping work?
Single crochet carries nearly the entire piece, with increases and decreases doing the rounding and closing. There is no need for any fancier stitch here.
Why does the stitch count decrease gradually near the end?
The gradual decrease rounds pull the rounded body back in toward the closing section. This tapering is what gives the finished piece its wedge-like shape before you cinch it shut.
