Cold wind cuts right through a standard hat, but this simple crochet ear warmer provides a cozy shield that stays firmly in place during brisk morning walks. It uses soft worsted weight yarn to create a thick, ribbed texture that feels gentle against the forehead without slipping off. Beginners will find this project approachable because it relies on basic half double crochet stitches worked in rows, meaning you only need to master one primary technique to finish the entire piece. It is a satisfying weekend project that fits neatly into a spare hour or two while you relax at home.

Why You’ll Love This Pattern

This beginner-friendly crochet coaster pattern uses a simple combination of double crochet stitches worked in joined rounds to create a dense, heat-resistant fabric. It is an ideal project for using up leftover yarn scraps from larger blanket projects. You can finish a complete set of four in a single afternoon, making these an excellent choice for last-minute housewarming gifts. The structural integrity provided by the joined rounds ensures these coasters remain flat and stable even after repeated use.

I managed to whip up a stack of these in just a few hours. The pattern is very easy to follow and they look professional enough to give as a gift to my coworkers.

Step-by-Step Pattern Instructions

Coaster Body

Work in joined rounds, chaining 2 at the start of each round (does not count as a stitch).

Rnd 1: Start with a MR, work 12 dc into the ring. Join with a sl st to the first dc. (12 sts)
Rnd 2: Ch 2, work 2 dc in each st around. Join with a sl st to the first dc. (24 sts)
Rnd 3: Ch 2, 1 dc in next st, inc in next st repeat from * to * around. Join with a sl st to the first dc. (36 sts)
Rnd 4: Ch 2, 1 dc in next 2 sts, inc in next st repeat from * to * around. Join with a sl st to the first dc. (48 sts)

Finishing

Fasten off your yarn, leaving a 6-inch tail. Use your tapestry needle to weave the yarn tail through the back of the stitches to secure it. If you prefer a decorative edge, you can perform a final round of crab stitch (reverse single crochet) to add a firm border, though the plain dc finish is sufficient for everyday use.

Care & Washing Instructions

Machine wash your cotton coasters on a gentle cycle in cold water.
Lay the coasters flat on a towel to air dry to prevent stretching or misshaping.
If the coasters become warped, lightly steam them with an iron while pulling them back into a flat circle.

Pro Tips & Common Mistakes to Avoid

Maintaining consistent tension is the primary way to ensure your coasters stay flat; if your circle starts to cup, try using a slightly larger hook.
Always place a stitch marker in the first stitch of every round to keep track of where your join belongs, as it can be easy to accidentally crochet into the turning chain.
Weave your ends in by threading the tail through the base of the stitches on the wrong side for at least two inches to ensure the end does not poke out during use.
To adjust the size, simply add or subtract rounds using the standard circle increase formula; remember that larger coasters will require more yarn yardage.

Frequently Asked Questions

Can I use a different yarn weight for this pattern?

Yes, you can use DK or bulky weight yarn. Keep in mind that changing the yarn weight will significantly alter the final size of the coaster. If you use a lighter weight yarn, you may need to add extra increase rounds to reach the desired diameter.

Is this pattern suitable for someone who has never held a crochet hook?

This is a great first project. It focuses on the three most common movements in crochet: the magic ring, the double crochet stitch, and the slip stitch join. You may want to practice your chain and dc stitches on a scrap piece of yarn before starting the official project.

Why do my coasters have a wavy edge instead of laying flat?

A wavy edge usually indicates that you have too many stitches for the circumference of the circle. Check your stitch counts against the instructions for each round. If your count is correct but it still waves, your tension may be too loose; try moving down one hook size.

Am I allowed to sell coasters I make using this design?

You are welcome to sell finished items made from this pattern as long as you credit the design and use your own photographs. You may not sell, distribute, or claim the written pattern as your own work.
