Crescent Moon Coaster Set Crochet Free Pattern

Introduction

These Crescent Moon Coasters are a sweet little project for anyone who is new to crochet and wants a finished piece they can actually use. Worked in soft, natural undyed worsted cotton, they have a calm, space-age look that fits right into a modern home. Each coaster starts as a simple flat circle and then narrows into a gentle crescent shape, so you get plenty of satisfying practice with single crochet, increases, and decreases. They are quick to make, easy to gift, and lovely stacked on a coffee table or tucked under a mug of something warm.

Materials Needed

• Yarn: Worsted weight (4) cotton yarn, undyed natural color, approximately 50 yards total for a set of 4 coasters.
• Hook: 4.5 mm (US 7) crochet hook.
• Notions: Stitch marker, tapestry needle for weaving in ends, and scissors.
• Finished size: Approximately 4.5 inches (11.5 cm) in diameter at the widest point.

Abbreviations

• MR: Magic ring — an adjustable loop you crochet into to start with no hole in the middle.
• sc: Single crochet — the basic short stitch.
• sl st: Slip stitch — a joining stitch that adds almost no height.
• ch: Chain — a loop of yarn used to start a round or row.
• st(s): Stitch(es).
• sc2tog: Single crochet two stitches together — a decrease that turns 2 stitches into 1.
• inc (2 sc in same st): Increase — work two single crochet into one stitch to add a stitch.

Gauge

16 single crochet stitches and 16 rows = 4 inches (10 cm). To check, crochet a small flat swatch and measure a 4-inch section across the middle; if it is wider, go down a hook size, and if it is narrower, go up.

Tips Before You Start

• Keep your tension even and relaxed — cotton shows tight stitches clearly, and a loose, even hand keeps the coaster flat.
• Use a stitch marker in the first stitch of each joined round so you never lose your place.
• When you begin the crescent rows, count carefully: you work only the first 18 stitches of the 36-stitch round, leaving the rest unworked to form the inner curve.
• Work the edging with a light touch so the border lies flat rather than ruffling.

Row 9: Ch 1, sc2tog twice. Turn. (2 sts)

Row 10: Ch 1, sc2tog. Fasten off. (1 st)

Edging

Join yarn at the bottom of the crescent (where you began Row 1). Ch 1, sc evenly around the entire outer edge of the crescent, working 2 sc in each corner and 1 sc in each row end. Join with sl st to first sc. Fasten off. Weave in ends.

Repeat the coaster and edging for all 4 coasters.

Assembly and Finishing

These coasters are worked in one piece, so there is no seaming to do. Weave in all loose ends on the wrong side with your tapestry needle, threading each end back through a few stitches before trimming. To block, mist each coaster lightly with water, shape it flat into a neat crescent on a towel or blocking mat, and let it dry completely; this helps the edges lie smooth and even. Stack the finished set or tie it with a ribbon for gifting.

Pro Tips and Variations

• Try a soft pastel or deep midnight blue cotton for a different moonlit look, or mix colors across the set.
• Add a second round of sc in a contrasting shade around the edging for a crisp outline.
• Work a slightly larger hook and add one more increase round to make bigger coasters or small moon-shaped appliqués.
