Why You’ll Love This Pattern

This beginner-friendly crochet coaster pattern uses a simple spiral construction, making it an excellent choice for those new to working in the round. You can complete a single coaster in under thirty minutes, which makes it a practical project for using up small amounts of leftover cotton yarn. The final piece provides a firm, heat-resistant surface that protects your furniture from condensation and warm mugs alike. Its classic circular shape ensures that it lays flat on any table surface without curling or warping.

I managed to finish a full set of six coasters in one weekend using my scrap bin yarn. The pattern is very easy to follow and they look great on my coffee table.

Pattern Overview & Skill Level

Skill Level: Beginner
Approximate Time: 20-30 minutes per coaster
Construction: Continuous rounds worked in a spiral
Finished Dimensions: Approximately 4 inches in diameter

Materials & Supplies Needed

Yarn: Worsted weight (#4) 100% cotton yarn, approximately 15 yards per coaster.
Hook Size: 5.0 mm (H-8) crochet hook.
Notions: Tapestry needle for weaving in ends, one stitch marker to track the start of rounds.
Safe yarn substitutions: You may use acrylic yarn, but note that it is less heat-resistant than cotton. Wool yarn will shrink if felted, so ensure you use superwash wool if you require machine washability.

Step-by-Step Pattern Instructions

Coaster Base

Work all rounds in a continuous spiral. Place a stitch marker at the beginning of each round to keep track of your position.

Rnd 1: Start with a MR. Work 6 sc into the ring. (6 sts)
Rnd 2: Work 2 sc in each st around. (12 sts)
Rnd 3: *1 sc in next st, inc in next st; repeat from * around. (18 sts)
Rnd 4: *1 sc in next 2 sts, inc in next st; repeat from * around. (24 sts)
Rnd 5: *1 sc in next 3 sts, inc in next st; repeat from * around. (30 sts)
Rnd 6: *1 sc in next 4 sts, inc in next st; repeat from * around. (36 sts)
Rnd 7: *1 sc in next 5 sts, inc in next st; repeat from * around. (42 sts)

Finishing

Once you reach the end of Round 7, work one sl st into the next stitch to level off the edge. Cut your yarn, leaving a 6-inch tail. Pull the tail through the final loop and use your tapestry needle to weave the end securely into the back of the coaster. Trim any excess yarn close to the fabric.

Care & Washing Instructions

Machine wash on a gentle cycle in cold water using a mild detergent.
Lay the coaster flat on a towel to air dry to prevent stretching or distortion.
If the coaster becomes misshapen, lightly dampen it and pin it flat to a blocking mat until completely dry.

Pro Tips & Common Mistakes to Avoid

Maintain consistent tension throughout the project to ensure the coaster remains flat. If your coaster begins to cup, your tension is likely too tight; switch to a larger hook. If it ruffles, your tension is too loose or you are adding too many stitches; check your counts against the provided totals. Always use a stitch marker at the start of each round to avoid losing your place in the increase sequence. To weave in ends invisibly, feed the yarn tail back and forth through the back loops of the stitches on the reverse side of the coaster rather than pulling through the entire fabric.

Frequently Asked Questions

Can I make these coasters larger?

Yes, you can continue the increase pattern by adding an extra single crochet between increases in every subsequent round. Note that this will require more yarn.

Is this pattern suitable for complete beginners?

Yes, this project is ideal for beginners as it focuses on basic single crochet stitches and the standard increase method used in most circular crochet items.

Can I sell the finished coasters I make?

You are welcome to sell finished items made from this pattern, but please credit the design to this tutorial. Do not sell or redistribute the written instructions themselves.

What happens if I use a different yarn weight?

Using a lighter yarn, like DK or fingering weight, will result in a smaller coaster. Using a bulky yarn will create a larger, thicker coaster; ensure you adjust your hook size to match the yarn weight for the best results.
