Why You’ll Love This Pattern

This beginner-friendly crochet coaster pattern uses a simple spiral construction, making it an ideal project for those just learning to work in the round. You can complete a single coaster in under thirty minutes, which makes it perfect for last-minute gifts or as a quick palate cleanser between larger, more demanding blanket projects. Because it relies on basic increases, it is a low-stress, relaxing project that works well while listening to a podcast or audiobook. Since each coaster uses only a small amount of yarn, you can easily use up leftover bits from previous projects to create a colorful, eclectic set for your coffee table.

I managed to finish a set of four coasters in one afternoon using yarn scraps I had lying around. The instructions were very easy to follow and the finished result lays perfectly flat on my desk.

Pattern Overview & Skill Level

Skill Level: Beginner
Approximate Time: 20–30 minutes per coaster
Construction: Continuous rounds starting from a magic ring
Finished Dimensions & Sizing: Approximately 4 inches in diameter

Materials & Supplies Needed

Yarn: Worsted weight (#4) cotton yarn. Cotton is preferred for coasters because it is absorbent and heat-resistant. Approximately 15 yards per coaster.
Hook Size: 5.0 mm (US H-8)
Notions: Tapestry needle for weaving in ends, scissors, and a stitch marker to track the beginning of your rounds.
Safe yarn substitutions: You may use acrylic yarn, but note that it is not heat-resistant and may melt if a hot mug is placed directly on it. Wool can be used but requires hand-washing to prevent felting.

Step-by-Step Pattern Instructions

Coaster Body

Work in a continuous spiral. Place a stitch marker in the first stitch of each round and move it up as you progress.

Rnd 1: Work 6 sc into a magic ring (6 sts).
Rnd 2: Work 2 sc in each st around (12 sts).
Rnd 3: 1 sc, inc repeat from * to * 6 times (18 sts).
Rnd 4: 1 sc, inc, 1 sc repeat from * to * 6 times (24 sts).
Rnd 5: 3 sc, inc repeat from * to * 6 times (30 sts).
Rnd 6: 2 sc, inc, 2 sc repeat from * to * 6 times (36 sts).

Finishing

Once you reach 36 stitches, join the final round with a sl st to the next stitch to create a smooth 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. 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 ensure it maintains its circular shape.
If the coaster becomes slightly warped after washing, dampen it lightly and press it under a heavy book for two hours to reshape.

Pro Tips & Common Mistakes to Avoid

Maintain consistent tension throughout the project to ensure the coaster lays flat; if your stitches are too tight, the circle will curl into a bowl shape. Always use a stitch marker at the start of each round, as it is easy to lose count when working in continuous spirals without a seam. When weaving in your ends, run the needle through the back loops of the stitches to keep the tail completely invisible from the right side. If you want a larger coaster, continue the pattern by adding an extra round of increases, though remember that this will increase the amount of yarn required for each piece.

Frequently Asked Questions

Can I use a larger hook for this pattern?

Using a larger hook will result in a looser, more open fabric and a larger finished diameter. You will also use slightly more yarn if you increase the hook size significantly.

Is this pattern suitable for complete beginners?

Yes, this is an excellent starter project. It introduces the magic ring and basic increases, which are the fundamental building blocks for nearly all circular crochet patterns.

How do I adjust the size of the coaster?

To make the coaster larger, continue the increase pattern by adding an additional round of increases (e.g., 5 sc, inc for the next round). To make it smaller, simply stop after round 4 or 5.

Can I sell the finished coasters?

You are welcome to sell finished items made from this pattern, provided you credit the designer in your product listings. Always check the specific terms provided by the pattern source if you are selling at scale.
