Pattern Overview & Skill Level

Skill Level: Beginner
Approximate Time: 15–20 minutes per coaster
Construction: Worked in continuous rounds starting from a center point with simple increases to maintain a flat shape
Finished Dimensions: Approximately 4 inches in diameter

Materials & Supplies Needed

Yarn: Worsted weight (#4) 100% cotton yarn, approximately 15 yards per coaster. Cotton is chosen for its absorbency and heat resistance.
Hook Size: 5.0 mm (H-8) crochet hook
Notions: Tapestry needle for weaving in ends, scissors, and a stitch marker to track the start of each round.
Yarn Substitutions: Acrylic yarn may be substituted but will be less absorbent and may melt if exposed to high heat from mugs. Wool yarn provides a natural look but requires hand washing to prevent felting.

Stitch Guide & Abbreviations (US Terms)

MR: Magic Ring (a method of starting a project by crocheting into an adjustable loop)
ch: Chain
sc: Single crochet
inc: Increase (work 2 sc into the same stitch)
sl st: Slip stitch

Step-by-Step Pattern Instructions

Coaster Body

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 each of the next 2 sts, 2 sc in next st repeat from * to * 6 times. (24 sts)
Rnd 5: 1 sc in each of the next 3 sts, 2 sc in next st repeat from * to * 6 times. (30 sts)
Rnd 6: 1 sc in each of the next 4 sts, 2 sc in next st repeat from * to * 6 times. (36 sts)

Finishing

Once you reach the end of Rnd 6, finish the circle by working one sl st into the first stitch of the round to create a smooth edge. Cut the yarn, leaving a 4-inch tail. Pull the tail through the loop on your hook to secure it. Thread the tail onto a tapestry needle and weave it through the stitches on the back side of the coaster to hide the end. Trim any excess yarn close to the fabric.

Care & Washing Instructions

Machine wash on a gentle cycle in warm water up to 40 degrees Celsius.
Lay the coaster flat on a clean towel to air dry, ensuring it is shaped into a perfect circle while damp.
If the coaster curls after washing, lightly dampen it and press with a warm iron to restore the flat shape.

Pro Tips & Common Mistakes to Avoid

Maintain consistent tension throughout the project to ensure the coaster remains flat rather than cupping or ruffling. If the coaster begins to cup like a bowl, your stitches are likely too tight; consider sizing up your hook. If the edge ruffles, your stitches are too loose, or you may have added extra increases by accident. Always place a stitch marker in the first stitch of every round to keep an accurate count and avoid working in a spiral for too long without checking your progress. To adjust the size, simply continue the increase pattern of 1 sc in each of the next X sts, 2 sc in next st for as many rounds as you prefer, noting that this will require more yarn.

Frequently Asked Questions

Can I use a larger hook size for this pattern?

Yes, using a larger hook will result in a larger, slightly more open coaster. Be aware that this will increase your yarn consumption per piece.

Is it possible to make these square instead of circular?

This specific pattern is designed for circular construction. To make a square, you would need a different pattern base involving corner increases in every row.

Can I sell the coasters I make from this pattern?

You are welcome to sell finished items created from this pattern. I ask that you credit the designer by including a link to this tutorial in your product listing.

What if I am new to the magic ring technique?

If you struggle with the magic ring, you can chain 3 and work your first round of stitches into the first chain you made. This creates a similar, though slightly larger, center hole.
