Crocheting a small mosaic coin charm is a fun, satisfying project that adds a charming geometric accent to your collection or gifts. This particular pattern uses chartreuse and cream cotton thread to create a visually striking checkerboard diamond motif through alternating colors in simple single crochet stitches. It’s ideal for beginners looking to practice color carry techniques while making a neat, modern accessory. The charm is quick to work up on a small 2mm hook, perfect for using leftover thread and creating unique handmade keychains or zipper pulls. I found that carrying the unused color gently behind the stitches keeps the mosaic pattern tidy and prevents tension from distorting the shape, which can be a helpful tip for anyone new to colorwork. If you enjoy small decorative projects that blend simplicity and style, this geometric pattern pairs nicely with other beginner-friendly projects like a soft floral crochet hair comb pattern, which also uses subtle color changes for eye-catching results.

Materials Needed
- Chartreuse cotton thread (size 10 crochet cotton recommended)
- Cream cotton thread (matching size 10)
- 2mm crochet hook
- Small jump ring or keyring
- Tapestry needle for weaving in ends
- Scissors
Stitches and Abbreviations
- ch = chain stitch: yarn over, pull through loop on hook
- sc = single crochet: insert hook, yarn over, pull up a loop, yarn over, pull through both loops on hook
Gauge and Tension Notes
Gauge is not critical for this tiny accessory but maintaining consistent tension is. Crocheting too tightly could make color carries difficult to work behind the stitches and may distort the mosaic design. Aim for a firm but flexible tension to help keep the coin charm flat and even.
Pattern Notes Before You Start
This charm is worked entirely in rounds using single crochet stitches. Color changes occur every stitch in the second and third rounds, carrying the unused color loosely behind the work to create the checkerboard mosaic effect. The offset color pattern in round three creates a diamond-shaped geometric look. There is no shaping beyond simple stitch count increases. After rounds are complete, fasten off, weave in ends, and attach the jump ring.
Step-by-Step Crochet Instructions
- Make a magic ring (adjustable loop).
- Round 1: ch1 (does not count as stitch), work 8 sc into the magic ring. Pull ring tight and join if preferred to form a round (8 sts).
- Round 2: Starting with chartreuse, alternate 1 sc chartreuse, 1 sc cream around, maintaining a total of 16 stitches. Carry the unused color loosely behind your stitches without pulling too tightly to avoid puckering (16 sts).
- Round 3: Repeat the alternating sc colors but offset by one stitch from round 2, which forms the diamond mosaic effect (16 sts).
- Fasten off both colors leaving tails long enough to weave in.
Assembly and Finishing
Use a tapestry needle to weave in all loose ends tidily on the back side of the charm. Attach a small jump ring through any stitch at the top edge, and then attach it to your keyring or desired bag accessory. Blocking is optional but gently shaping the charm into a flat disc while damp can help the geometric pattern lay neatly.
Helpful Tips
- Keep your color carries loose behind stitches—too tight will pucker the surface.
- Use a stitch marker at the beginning of your rounds if you prefer to join rounds for neatness.
- If you’re unfamiliar with magic rings, practice this first as the foundation of your charm.
- Holding both thread colors in one hand as you work can make color changes smoother.
- For a flatter feel, use slightly looser tension or consider lightly steaming/blocking the finished piece.
Common Mistakes to Avoid
- Pulling color threads too tightly, which will distort the mosaic effect.
- Forgetting to alternate colors consistently in round 2 and 3, breaking the checker pattern.
- Not weaving in ends securely, which can cause unraveling from daily use.
- Skipping the magic ring step and starting with chains can produce a hole in the center.
- Miscounting stitches—always confirm 8 sts in round 1 and 16 sts in rounds 2 and 3.
Customization Ideas
- Swap chartreuse and cream for any contrasting color pair (try pastel pink and white for softer look).
- Use finer or thicker thread for smaller or larger charms.
- Add a tiny bead or charm inside the jump ring for extra sparkle.
- Create multiple coins and join them for a chunky geometric keychain or necklace.
- Experiment with metallic thread for a festive touch.

Frequently Asked Questions
Q: Can I use a different hook size?
A: Yes, but keep in mind a larger hook will produce a looser fabric and larger charm, while a smaller hook makes it tighter and smaller. Adjust tension accordingly.
Q: What if I want a solid color instead of mosaic?
A: Simply choose one color and crochet all stitches the same throughout each round.
Q: How do I avoid holes in the magic ring center?
A: Pull the magic ring tight after round 1, and if preferred, sew the starting tail end through the back to close minor gaps.
Q: Can this pattern be made into a bigger motif?
A: Not as-is, since the mosaic pattern relies on 16 stitches in rounds 2 and 3. However, you could develop additional rounds by following mosaic layouts.
Q: What if I find color carrying tricky?
A: Try holding both yarns in one hand to smooth tension or experiment with color-changing techniques as shown in other beginner patterns which you can find alongside this one.
