About This Sun & Rainbow Key Chains Pattern
This pattern shows you how to crochet sweet sun and rainbow key chains using mercerized cotton yarn and a 3mm hook. The designs are no-sew or minimal sew, making them fast and fun to make. Perfect as little gifts, bag charms, or colorful accessories.
You will learn simple rounds, working BLO/FLO to create texture, and a small decorative edging to finish each piece. The pattern includes cheek roses and embroidered faces for personality.
Why You'll Love This Sun & Rainbow Key Chains Pattern
I absolutely love this pattern because it brings bright, happy motifs to life with very little time investment. I enjoy how quickly each charm comes together and how customizable the colors are. I love adding tiny embroidered faces and rose cheeks to give each piece a unique personality. Making a set of these always lifts my mood and they make perfect last-minute gifts.
Switch Things Up
I love customizing these key chains by changing the color palette; try pastel shades for a softer look or neon brights for extra pop.
I sometimes use a thicker yarn and a larger hook to make chunkier, more plush charms that double as small toys.
I also enjoy making mini versions using finer thread and a smaller hook to turn them into delicate jewelry pendants.
For a sparkly option, I add a strand of metallic thread held together with the main color for subtle shine.
You could replace the crochet cheeks with tiny felt circles sewn on for a different texture and look.
I often embroider different facial expressions to give each charm its own personality—experiment with eye shapes, smiles, and blush placement.
Try adding a tiny bell or bead inside the loop for a jingling key ring that’s perfect for kids' bags.
If you want posable charms, insert a short length of thin wire into the loop area before closing to keep it firm and bendable.
I sometimes stitch a contrasting border around the rainbow or sun to make the outline stand out and look more finished.
Finally, make a matching set of both sun and rainbow charms as a gift, mixing and matching colors for a coordinated collection.
Common Mistakes & How to Fix Them
✗ Skipping the BLO/FLO instructions will change the look of the rays or edges; follow the BLO/FLO directions exactly as written to keep the correct texture.
✗ Not stuffing firmly will leave the sun or rainbow limp and misshapen; stuff firmly and evenly while shaping to achieve the intended roundness.
✗ Missing the stitch counts after increases and decreases leads to uneven shaping; count your stitches at the end of each round to confirm accuracy.
✗ Closing the loop incorrectly can create a visible gap; use a tapestry needle to close the loop neatly and weave the tail securely.
✗ Pulling your yarn too tight when embroidering the face can distort the front surface; use gentle tension and test placement before final stitches.
