Sun-Kissed Dahlia Coaster Set Free Crochet Pattern – Layered Petal Blooms

Bring a garden-fresh vibe to your table with these dimensional dahlia coasters, each petal crocheted in soft cotton and stacked for a lush, sculptural look. This pattern is a delightful weekend project that turns simple stitches into a blooming work of art. Whether you're dressing up a coffee table or looking for a heartfelt handmade gift, these coasters are as practical as they are beautiful—and they're beginner-friendly, too!

Using just basic stitches like single crochet, double crochet, and half double crochet, you'll create a textured flower that looks intricate but comes together surprisingly quickly. The secret lies in the layered shell-stitch petals, which give each coaster a ruffled, dimensional appearance reminiscent of a real dahlia bloom. Let's dive in and make your table bloom!

Materials Needed

Before you begin, gather the following supplies. All items are readily available at craft stores or online.

• Yarn: Worsted weight cotton yarn (e.g., Lion Brand 24/7 Cotton) in 3 colors:
  • Petal Color A (e.g., coral) – for the base and first petal layer
  • Petal Color B (e.g., peach) – for the second petal layer
  • Center Color C (e.g., golden yellow) – for the puffy center
• Crochet Hook: US G/6 (4.0 mm) crochet hook
• Yarn needle for weaving in ends
• Scissors
• Pins and steam iron or spray bottle (for blocking, optional but recommended)

Gauge: First 3 rounds of coaster = 2 inches in diameter. Exact gauge is not critical for this project, but maintaining consistent tension will help your petals lie flat and even.

Finished Size: Each coaster measures approximately 4 inches in diameter—perfect for standard mugs and glasses.

Step-by-Step Instructions

This pattern is worked in continuous spirals for the base, then petals are added in rounds. Follow along carefully, and you'll have a gorgeous dahlia coaster in no time. The instructions below are for one coaster; repeat for as many as you'd like to make a full set.

Base (Worked in Color A)

The base forms the flat circular foundation of your coaster. It's worked in single crochet with increases in each round.

Round 1: Make a magic ring. Chain 1 (does not count as a stitch), work 6 single crochet (sc) into the ring. Pull the tail tight to close the ring. Join with a slip stitch (sl st) to the first sc. (6 stitches)

Round 2: Chain 1, work 2 sc in each stitch around. Join with a sl st to the first sc. (12 stitches)

Round 3: Chain 1, *sc in the next stitch, 2 sc in the next stitch*; repeat from * to * around. Join with a sl st. (18 stitches)

Round 4: Chain 1, *sc in the next 2 stitches, 2 sc in the next stitch*; repeat from * to * around. Join with a sl st. (24 stitches)

Round 5: Chain 1, *sc in the next 3 stitches, 2 sc in the next stitch*; repeat from * to * around. Join with a sl st. (30 stitches)

Fasten off Color A. Your base should be a flat, even circle about 2.5 inches in diameter.

First Petal Layer (Color A)

Now we'll add the first set of petals using shell stitches. These create the scalloped, dimensional look of the dahlia.

Round 6: Join Color A in any stitch of Round 5. Chain 3 (counts as a double crochet, dc), work 1 dc in the same stitch. Chain 2, skip 1 stitch. *Work 2 dc in the next stitch, chain 2, skip 1 stitch*; repeat from * to * around. Join with a sl st to the top of the beginning chain-3. (15 petal bases)

Round 7: Slip stitch into the next chain-2 space. Chain 3 (counts as dc), work 2 dc, chain 2, 3 dc all in the same space—this completes your first petal. *In the next chain-2 space, work 3 dc, chain 2, 3 dc*; repeat from * to * around. Join with a sl st to the top of the beginning chain-3. Fasten off Color A. (15 petals)

You'll notice the petals are beginning to ruffle slightly—that's exactly what we want for a dahlia effect.

Second Petal Layer (Color B)

This layer sits on top of the first, adding depth and a beautiful color contrast.

Round 8: Join Color B in any chain-2 space of Round 7. Chain 3 (counts as dc), work 2 dc, chain 2, 3 dc all in the same space. *In the next chain-2 space, work 3 dc, chain 2, 3 dc*; repeat from * to * around. Join with a sl st to the top of the beginning chain-3. Fasten off Color B. (15 petals)

Because this layer is worked into the chain-2 spaces of the previous round, the petals will naturally sit slightly offset and appear larger, giving your coaster a lush, layered look.

Center (Color C)

The final touch is a puffy, textured center that mimics the heart of a dahlia.

Round 9: Join Color C in any chain-2 space of Round 8. Chain 2 (counts as a half double crochet, hdc), work 2 hdc, chain 1, 3 hdc all in the same space. *In the next chain-2 space, work 3 hdc, chain 1, 3 hdc*; repeat from * to * around. Join with a sl st to the top of the beginning chain-2. Fasten off Color C.

The chain-1 spaces between the hdc clusters create a subtle opening that adds texture and visual interest to the center.

Finishing

Now for the final touches that will make your coaster look professionally made.

1. Weave in all ends using your yarn needle. Be sure to weave them securely on the wrong side of the work so they don't show on the front.
2. Block your coaster gently. Pin it to a flat surface, shaping the petals so they lie evenly. Steam lightly with an iron held a few inches above the work (do not press directly) or mist with water and let dry completely. This step helps the petals lay flat and gives your coaster a polished, finished look.
3. Repeat the entire pattern to create as many coasters as you'd like for your set.

Tips for Success

• Keep your tension consistent. Cotton yarn has less give than wool, so try to keep your stitches even to avoid puckering.
• Count your stitches after each round, especially in the base, to ensure your circle stays flat.
• Use a stitch marker if you find it helpful, though the join at the end of each round makes counting easy.
• Experiment with colors! Try sunset oranges and reds, or cool blues and purples for a different vibe. The pattern works beautifully in any color combination.

These Sun-Kissed Dahlia Coasters are more than just practical—they're a tiny piece of art for your home. The layered petals and warm, sun-kissed colors evoke a summer garden, bringing a touch of nature indoors.
