Patterned Pillars Mosaic Crochet Square Design – Free pattern
Ready for a mosaic crochet square design that’s both bold and soothing to stitch? The Patterned Pillars Square builds from the center out in a beautifully balanced way, creating striking geometric lines with a strong, grounded feel. Check out the free pattern and chart below and put your own spin on this eye-catching design.
The vertical lines in this mosaic crochet square give it a bit of an architectural feel, like tiny pillars anchoring the design. But it never feels too rigid or formal. The stepped details throughout soften the look just enough for a square that’s structured, but in a comforting, predictable way. It’s the kind of pattern that keeps your hands busy and your mind relaxed.
Notice anything odd about this square? It has a wide, white border. Why? Well, simply because I ran out of pink yarn. Oops! Oh well! I made it work by finishing my rounds off with just BLOsc using Color A. You can do that, or continue working the intuitive pattern—your choice!
At a Glance
- Finished Size: 12” x 12″ square
- Skill Level: Easy
- Technique(s): Overlay mosaic crochet in the round, from the center out
- Yarn: Worsted/medium (#4) weight yarn
- Hook: H/8 (5.00mm)
A Mosaic Crochet Square Design Worked in the Round
The Patterned Pillars Square is worked using overlay mosaic crochet in the round, a technique that creates bold, graphical designs by stitching over previous rounds. Rather than working through both loops, you’ll make your single crochets in the back loop only. Then some double crochets will drop down to pick up the unworked front loops from earlier rounds. Those overlay stitches are what bring the design to life.
Mosaic crochet can look a little intimidating at first, but it’s surprisingly approachable once you get started. This pattern uses only simple single and double crochet stitches, repeated in a relaxing rhythm that quickly starts to click. Before long, you’ll be watching the design grow round by round without even thinking about the technique.
Because this square is worked in the round, the yarn is carried along as you crochet instead of being cut after every round. That means far fewer ends to weave in—and more uninterrupted stitching time while the pattern unfolds.
If you’re brand new to overlay mosaic crochet, don’t worry! You can check out my YouTube tutorial that walks you through the technique step-by-step from the center out.

Pattern Notes
- Pattern is overlay mosaic crochet worked in the round from the center out. Watch this video to learn more about how to mosaic crochet from the center out. *Note: This video demonstrates the technique on another pattern but the basics are the same.
- Ch 1 at the beginning of a round does not count as a stitch.
- If you tend to have loose tension when you crochet, you may need to go down a hook size or choose a light worsted weight yarn to make this a 12″ square.
- Sts between *asterisks* are repeated on each side of the square
- Each round (except Round 1) begins with the corner sts.
- The Corner stitches (BLOsc, ch1, BLOsc) are worked together into the BLO of the ch1 of the corner in the row below.
- Carry the unworked yarn under the first BLOsc of each corner, then drop the unworked yarn to the wrong side of the work and continue working.
- The single FLOdc worked just before & after the corners are worked into the same ch st. (See Rounds 7, 8, 12, 13, 19, and 20)
- Work an invisible join after each round.
- You can add a wide, white border as written. Or if you prefer, you can keep going in the pillars pattern all the way to the edge. This motif is intuitive once you get going.
- A chart for this pattern is included as well.
