Why You’ll Love This Pattern

This beginner-friendly crochet coaster set is the ideal project for using up small amounts of leftover cotton yarn. Because each coaster is worked in simple, continuous rounds, it allows you to practice essential amigurumi-style increase techniques without the complexity of a 3D shape. The dense, flat surface of these coasters provides excellent heat protection for your tabletops while maintaining a clean, modern aesthetic. Most crocheters find they can finish a single coaster in under thirty minutes, making them a productive choice for a weekend afternoon or a last-minute handmade gift.

I managed to finish a full set of four coasters in one evening. The pattern is very easy to follow and the finished result lies completely flat without curling.

Pattern Overview & Skill Level

Skill Level: Beginner
Approximate Time: 25 minutes per coaster
Construction: Worked in joined rounds, starting with a magic ring and expanding with consistent increases to create a flat circle.
Finished Dimensions & Sizing: Approximately 4.5 inches in diameter when using worsted weight cotton.

Materials & Supplies Needed

Yarn: Worsted weight #4 cotton yarn. Approximately 15 yards per coaster. Cotton is required for its heat resistance and absorbency.
Hook Size: 5.0 mm (US H-8) crochet hook.
Notions: Tapestry needle for weaving in ends, a pair of sharp scissors, and a locking stitch marker to track the start of each round.
Safe yarn substitutions: You may use a bamboo/cotton blend for a softer feel, though this may result in a slightly thinner coaster. Avoid acrylic yarn, as it can melt when in contact with hot mugs.

Step-by-Step Pattern Instructions

Coaster Body

Work all rounds in a continuous spiral unless otherwise noted. Use a stitch marker to track the first stitch of every round.

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

Finishing and Joining

Once you reach the end of Rnd 7, do not perform another increase. To create a clean edge, work one final round of slip stitches into the front loop of every stitch around the perimeter. This provides a finished, professional look to the coaster and helps the outer edge maintain its shape. Fasten off, leaving a 6-inch tail. Use your tapestry needle to weave the yarn tail securely into the back of the coaster, trimming any excess yarn flush with the fabric.

Care & Washing Instructions

Machine wash on a gentle cycle in cool water to prevent color bleeding and shrinkage.
Lay the coasters flat on a clean towel to air dry, pressing them into a perfect circle while damp to ensure they remain flat.
Avoid using fabric softener, as it reduces the absorbency of the cotton fibers needed to catch condensation from cold drinks.

Pro Tips & Common Mistakes to Avoid

Maintain consistent tension throughout the project; if your tension is too loose, the coaster will ripple instead of lying flat.
Always place a stitch marker in the first stitch of each round to avoid losing your count, especially since you are working in a spiral.
When weaving in ends, pass the needle through the stitches on the back side of the coaster in at least two different directions to ensure the yarn does not pull out during use.
To adjust the size, simply add more increase rounds; for every additional round, you must add 6 stitches to keep the circle flat, and note that you will need approximately 5-8 additional yards of yarn per round.

Frequently Asked Questions

Can I use a larger hook to make these coasters bigger?

Yes, increasing your hook size will result in a larger coaster. However, keep in mind that a larger hook creates larger gaps between stitches, which might reduce the effectiveness of the coaster in catching drips from a mug.

Are these coasters suitable for a beginner?

These are excellent for beginners because they only use the single crochet stitch and the magic ring technique. If you find the magic ring difficult, you can substitute it by chaining 4 and slip stitching into the first chain to form a circle.

Is it okay to sell items made from this pattern?

You are welcome to sell finished items created from this pattern. Please credit the original design when listing your products online to support independent pattern development.

Why is my coaster curling at the edges?

Curling usually occurs if your tension is too tight or if you have skipped an increase in one of the rounds. If you notice curling, try going up half a hook size or ensure you are adding the full 6 stitches per round consistently.
