Why You’ll Love This Pattern

This beginner-friendly crochet coaster pattern uses simple single crochet stitches and a tight tension to create a sturdy, heat-resistant surface for your mugs. Because these coasters work up in under thirty minutes, they serve as a practical way to use up leftover cotton yarn from larger projects. The compact circular construction ensures the edges remain flat without the need for complex blocking techniques. You can easily adjust the size of these coasters by adding or subtracting increase rounds to fit everything from small espresso cups to oversized tea mugs.

These coasters were exactly what I needed to finish off my scrap yarn stash. The pattern is very easy to follow and they lay perfectly flat on my coffee table without curling up at the edges.

Pattern Overview & Skill Level

Skill Level: Beginner
Approximate Time: 20-30 minutes per coaster
Construction: Working in continuous rounds starting with a magic ring, increasing by 6 stitches every round to maintain a flat circle.
Finished Dimensions: Approximately 4 inches in diameter when using worsted weight yarn.

Materials & Supplies Needed

Yarn: Worsted weight (#4) 100% cotton yarn, approximately 15 yards per coaster. Cotton is essential for heat resistance and absorbency.
Hook Size: 4.5 mm (US 7) or 5.0 mm (US H-8) depending on your tension.
Notions: Tapestry needle for weaving in ends, one stitch marker to track the start of rounds.
Yarn Substitutions: Acrylic yarn is not recommended as it may melt under hot mugs. Wool can be used but will felt if washed frequently. If you choose a lighter weight yarn like DK, expect a finished size closer to 3 inches unless you add additional rounds.

Step-by-Step Pattern Instructions

Coaster Body

Rnd 1: Start with a MR. Work 6 sc into the ring. Place your marker in the first stitch. (6 sts)
Rnd 2: Work 2 sc in each st around. (12 sts)
Rnd 3: 1 sc, inc 6 times. (18 sts)
Rnd 4: 2 sc, inc 6 times. (24 sts)
Rnd 5: 3 sc, inc 6 times. (30 sts)
Rnd 6: 4 sc, inc 6 times. (36 sts)

Finishing

Once you reach the final round, slip stitch into the next stitch to smooth out the edge. Cut your yarn, leaving a 6-inch tail. Pull the tail through the loop and use your tapestry needle to weave the end securely into the back of the work. If you prefer a decorative edge, you can substitute the final round with a crab stitch (reverse single crochet) for a rope-like border.

Care & Washing Instructions

Machine wash on a gentle cycle in warm water (max 40 degrees Celsius) to remove condensation rings or drink spills.
Reshape the coaster by hand while damp and lay it flat on a clean towel to air dry.
Avoid using fabric softener, as this reduces the natural absorbency of the cotton fiber.

Pro Tips & Common Mistakes to Avoid

To ensure your coaster remains flat, keep your tension tight; if the center of the coaster begins to cup upward, your stitches are likely too loose. Always use a stitch marker at the beginning of each round to prevent losing track of your count, as these small circles can be deceptive. When weaving in your ends, work the yarn tail through the underside of the stitches in two different directions to prevent it from slipping out during wash cycles. If you want a larger coaster, continue the increase pattern by adding one more stitch between increases every round (e.g., 5 sc, inc) but be aware that this will require more yardage.

Frequently Asked Questions

Can I use variegated yarn for these coasters?

Yes, variegated yarn looks excellent for this project. Since the pattern is worked in a circular spiral, the color changes will create a subtle swirl effect throughout the coaster.

How do I keep the circle from becoming a hexagon?

The hexagon shape occurs if you make your increases in the exact same spot every round. To avoid this, you can stagger your increases by starting a round with a different number of single crochets before your first increase.

Are these coasters safe to sell?

You are welcome to sell finished items made from this pattern. I ask that you credit the design and use your own photographs for your product listings.

Can I make these coasters thicker?

You can hold two strands of yarn together while crocheting to create a thicker, more cushioned coaster. If you do this, you will need to size up your hook to at least a 6.0 mm (J-10) to maintain a workable gauge.

Your finished infinity scarf provides a soft, warm addition to any wardrobe, especially when styled in a neutral tone like oatmeal or slate grey. If you want a slightly thicker look for deeper winter, try holding two strands of lighter yarn together to achieve a chunky effect.
