This free mosaic crochet square pattern uses simple stitches to create an eye-catching mosaic heart design. Make it in holiday colors for Christmas or coordinate it with other squares. This pattern is part of the Moogly CAL 2024.


Do you ever get bored making a whole afghan from one stitch? Sometimes it’s nice to work on a easy project while watching TV or chatting with friends. But other times, you want to try something new. That’s why sampler blankets are so much fun. Each of the individual squares is a different pattern so they are a great way to try out different techniques.

The special thing about this particular sampler afghan is that it’s made up of a variety of patterns, each one designed by a different talented crochet designer. Even better, it’s a crochet along (or CAL). Tamara hosts the Moogly CALs each year, where hundreds of crocheters work on the same project at the same time. It’s a fun way to connect with other crocheters and share your progress as you complete a bigger project. If you want to learn more about Tamara, you can watch the episode of Nicki’s Crochet Podcast where I interviewed her.

My linked mosaic crochet heart Afghan square is the 20th one for 2024. Here you will find the free pattern as well as a companion video tutorial for you to help you complete the pattern. This block uses the overlay mosaic crochet technique. This is a colorwork technique that creates what looks like intricate designs without having to change colors within a row. But actually, overlay crochet is doable for any skill level, even beginners, as it uses just basic single and double crochet stitches.

Moogly CAL 2024

I’m so honored that Tamara has once again asked and featured me in her 2024 Moogly CAL. Each year, she invites 24 designers to contribute 24 squares to an afghan, which she crochets throughout the year. All of these crochet creations come together and the end result is a beautiful and unique blanket.

Afghan Square Pattern Notes

If you can’t meet the gauge or your square is too small at the end (can’t reach 12 Inches when blocking), simply repeat the last round or add a few sc rounds at the end. If your square is too large, replace the last round with an sc round OR switch hooks (smaller one) to meet the gauge.

Ch 1 or 2 at the beginning of the rounds don’t count as a stitch.

All slip stitches are made to the first st made. Personally, I use the invisible sl st (pull last loop from front to back through the first st). ATC stitches (stacked sc stitches) can be replaced with Ch3 and count as stitches.

ALL first DC stitches are ATC stitches (or ch 3 if you prefer).
