Lavender Mint Coaster Mandala Free Crochet Pattern

Introduction

This Lavender Mint Coaster Mandala is the perfect project for anyone who has mastered the basic double crochet and wants to make something that looks far more intricate than it really is. Worked in the round from a simple magic ring, it grows into a flat 10-inch disc of alternating lavender and mint rings, finished with a soft scalloped shell border. The DK acrylic yarn gives it a smooth, springy feel and a gentle coastal-grandmother charm that suits a coffee table, a bedside stand, or a wall display. Best of all, there is no shaping, no seaming, and no stress — just one continuous, meditative round after another.

Materials Needed

• Yarn: DK weight (category 3) anti-pilling acrylic — approximately 100 yards lavender (Color A) and 80 yards mint (Color B)
• Hook: 4 mm (US G/6)
• Notions: Tapestry needle for weaving in ends, scissors, stitch marker (optional, for marking the first stitch of each round)
• Finished size: 10 inches in diameter

Abbreviations

• ch — chain: yarn over and pull through the loop on your hook
• dc — double crochet: yarn over, insert hook in stitch, pull up a loop, yarn over and pull through 2 loops, yarn over and pull through the last 2 loops
• sc — single crochet: insert hook in stitch, pull up a loop, yarn over and pull through both loops
• sl st — slip stitch: insert hook in stitch, yarn over and pull through both the stitch and the loop on your hook
• st / sts — stitch / stitches
• rep — repeat
• [ ] — work everything inside the brackets the number of times stated

Gauge

4 rounds = 3.5 inches in double crochet. To check, work the first 4 rounds of the pattern and measure straight across the center of the circle; if your disc is larger than 3.5 inches, go down a hook size, and if it is smaller, go up one.

Tips Before You Start

• Count every round. The increases are evenly spaced, so a missed stitch will throw off the next round and make the disc ruffle. Count your stitches before joining each round.
• Change colors at the join. Finish the round with a slip stitch in the new color so the color change sits neatly at the join rather than mid-round.
• Keep your tension relaxed. A slightly loose, even tension keeps the disc flat; tight stitches make the outer rounds cup upward.
• Mark the first stitch. Place a stitch marker in the first stitch of each round so you always know where to join.

Step-by-Step Instructions

Work in the round, joining each round with a sl st to the first stitch. Change colors as noted at the start of each round.

Rnd 1 (A): Make a magic ring, ch 3 (counts as first dc), 11 dc in ring, join with sl st to top of ch-3. (12 dc)

Rnd 2 (B): Ch 3, dc in same st, 2 dc in each st around, join. (24 dc)

Rnd 3 (A): Ch 3, dc in same st, dc in next st, *2 dc in next st, dc in next st; rep from * around, join. (36 dc)

Rnd 4 (B): Ch 3, dc in same st, dc in next 2 sts, *2 dc in next st, dc in next 2 sts; rep from * around, join. (48 dc)

Rnd 5 (A): Ch 3, dc in same st, dc in next 3 sts, *2 dc in next st, dc in next 3 sts; rep from * around, join. (60 dc)

Rnd 6 (B): Ch 3, dc in same st, dc in next 4 sts, *2 dc in next st, dc in next 4 sts; rep from * around, join. (72 dc)

Rnd 7 (A): Ch 3, dc in same st, dc in next 5 sts, *2 dc in next st, dc in next 5 sts; rep from * around, join. (84 dc)

Rnd 8 (B): Ch 3, dc in same st, dc in next 6 sts, *2 dc in next st, dc in next 6 sts; rep from * around, join. (96 dc)

Rnd 9 (A): Ch 3, dc in same st, dc in next 7 sts, *2 dc in next st, dc in next 7 sts; rep from * around, join. (108 dc)

Rnd 10 (B): Ch 3, dc in same st, dc in next 8 sts, *2 dc in next st, dc in next 8 sts; rep from * around, join. (120 dc)

Shell Border (Round 11)

Rnd 11 (A): Ch 1, sc in same st, *skip 2 sts, 5 dc in next st (shell made), skip 2 sts, sc in next st; rep from * around, join with sl st to first sc. (20 shells)

Fasten off.

Assembly and Finishing

There is no seaming — this mandala is a single continuous piece. Weave in all ends on the wrong side with your tapestry needle, running each tail under several stitches in the same color so it disappears. Block the mandala to 10 inches in diameter: mist it lightly with water, pin it out flat on a blocking mat, and let it dry completely. Blocking opens up the shell border and ensures the disc lies perfectly flat.

Pro Tips and Variations

• Swap the palette: Try cream and sage, or blush and terracotta, for a different coastal look — just keep the two colors alternating by round.
• Make a set: Work four coasters in the same colors and stack them, or vary the color order for a coordinated mismatched set.
• Add a hanging loop: Before fastening off, ch 12 and sl st back to the border to create a small loop so the mandala can hang on a wall.
