Materials Needed

Before you begin, gather the following supplies to ensure a smooth and enjoyable crochet experience:

• Yarn: Worsted weight cotton yarn in three colors:
  • Sea Glass (light aqua) – approximately 30 yards
  • Sand (warm beige) – approximately 20 yards
  • Coral (soft pink) – approximately 15 yards
• Hook: US G/6 (4.0 mm) crochet hook
• Notions: Yarn needle for weaving in ends and creating the woven center, scissors
• Gauge: First 3 rounds = 2 inches in diameter (gauge is not critical, but maintaining consistent tension ensures a flat, even coaster)

Finished Size & Special Stitches

Finished Size: Approximately 4 inches in diameter.

Special Stitches & Abbreviations:

• Magic ring (MR): An adjustable loop that allows you to pull the center tightly closed.
• Chain (ch), slip stitch (sl st), single crochet (sc), half double crochet (hdc), double crochet (dc), treble crochet (tr)
• Picot: Ch 3, sl st in first ch (creates a small decorative loop).
• Woven stitch: Working through front loops only (FLO) and back loops only (BLO) to create texture—this pattern uses a woven center technique described in the final step.

Step-by-Step Instructions

Follow these detailed instructions carefully. Each round builds upon the previous one, creating a beautiful layered flower. Work in continuous rounds unless otherwise noted, and always join with a slip stitch as indicated.

Round 1 (Coral): The Center

With Coral yarn, make a magic ring. Ch 2 (this counts as your first hdc). Work 11 hdc into the ring. Pull the ring closed tightly. Join with a sl st to the top of the ch 2. (12 hdc total)

Round 2 (Coral): Expanding the Center

Ch 2 (counts as hdc). Hdc in the same stitch (the base of the ch 2). Work 2 hdc in each stitch around. Join with a sl st to the top of the ch 2. (24 hdc total)

Round 3 (Sand): Creating the First Petal Base

Ch 1. Sc in the same stitch. *Ch 3, skip the next stitch, sc in the following stitch.* Repeat from * to * around, ending with ch 3, then sl st to the first sc. (12 ch-3 spaces)

Round 4 (Sand): First Layer of Petals

Sl st into the first ch-3 space. Ch 1. In the same space, work: (sc, hdc, dc, picot, dc, hdc, sc). *In the next ch-3 space, work the same sequence: (sc, hdc, dc, picot, dc, hdc, sc).* Repeat from * to * around. Join with a sl st to the first sc. (12 small petals created)

Round 5 (Sea Glass): Preparing for the Middle Layer

Ch 1. Sc in the same stitch (the sc between petals). *Ch 5, skip to the next petal, sc in the sc between petals (the sc from Round 3).* Repeat from * to * around, ending with ch 5. Join with a sl st to the first sc. (12 ch-5 spaces)

Round 6 (Sea Glass): Middle Layer of Petals

Sl st into the first ch-5 space. Ch 1. In the same space, work: (sc, hdc, 3 dc, picot, 3 dc, hdc, sc). *In the next ch-5 space, work the same sequence: (sc, hdc, 3 dc, picot, 3 dc, hdc, sc).* Repeat from * to * around. Join with a sl st to the first sc. (12 larger petals)

Round 7 (Sea Glass): Preparing for the Outer Layer

Ch 1. Sc in the same stitch. *Ch 6, skip to the next petal, sc in the sc between petals (from Round 5).* Repeat from * to * around, ending with ch 6. Join with a sl st to the first sc. (12 ch-6 spaces)

Round 8 (Sea Glass): Outer Layer of Petals

Sl st into the first ch-6 space. Ch 1. In the same space, work: (sc, hdc, 2 dc, 2 tr, picot, 2 tr, 2 dc, hdc, sc). *In the next ch-6 space, work the same sequence: (sc, hdc, 2 dc, 2 tr, picot, 2 tr, 2 dc, hdc, sc).* Repeat from * to * around. Join with a sl st to the first sc. (12 final, elongated petals)

Round 9 (Sand): Adding a Delicate Border

Ch 1. Sc in the same stitch. *Ch 4, skip to the next petal, sc in the sc between petals (from Round 7).* Repeat from * to * around, ending with ch 4. Join with a sl st to the first sc. (12 ch-4 spaces)

Round 10 (Sand): Final Petal Accents

Sl st into the first ch-4 space. Ch 1. In the same space, work: (sc, hdc, dc, picot, dc, hdc, sc). *In the next ch-4 space, work the same sequence: (sc, hdc, dc, picot, dc, hdc, sc).* Repeat from * to * around. Join with a sl st to the first sc. (12 small accent petals)

Finishing & The Woven Center

Fasten off and weave in all loose ends with your yarn needle. Gently block the coaster to shape—this helps the petals lie flat and enhances the stitch definition.

To create the woven center: Cut a 12-inch length of Sea Glass yarn. Thread it through a yarn needle. Weave the yarn over and under the hdc stitches in the center of the coaster (Rounds 1 and 2) in a spiral pattern, pulling gently to create a textured, sea-foam-like center. Secure the ends on the back of the coaster.

Tips for Perfect Results

• Maintain even tension: Consistent tension is key to a flat, round coaster. If your coaster begins to ruffle, your tension may be too loose; if it cups, it may be too tight.
• Blocking: Wet blocking (spritzing with water and pinning to shape) will give your coaster a professional, polished finish.
• Color variations: Feel free to experiment with different color combinations to match your home decor—the pattern is versatile!

Repeat these steps to create a full set of coasters. They make wonderful gifts and add a touch of coastal charm to any table. Enjoy your crafting journey!
