Soft wool against your skin provides warmth during the coldest months of the year, especially when that warmth comes from a hat you made yourself. This chunky hat project relies on a simple stitch combination that creates a thick, squishy fabric capable of holding its shape through many winters. You will find that the bulkiness of the yarn helps the project grow quickly, making it a great choice for those who need a thoughtful gift in a hurry. Beginners will appreciate how the basic stitch counts remain consistent throughout the construction, while experienced makers enjoy the rhythmic, meditative quality of working with larger hooks and thick, satisfying strands of wool.

Why You’ll Love This Pattern

This beginner-friendly crochet coaster set features a timeless, dense texture created by the moss stitch. Because it uses a simple two-row repeat, it is a highly relaxing project that works up quickly even for those with limited time. The square design provides a sturdy surface for mugs, effectively protecting your wooden tables from heat and moisture. You can easily adjust the size to make larger hot pads simply by adding more chains to your starting foundation. These coasters make for an excellent scrap-yarn project, as each one requires less than 20 yards of medium-weight cotton.

I managed to finish a full set of four coasters in a single evening. The pattern is incredibly easy to memorize and the end result is professional and clean.

Pattern Overview & Skill Level

Skill Level: Beginner
Approximate Time: 30 minutes per coaster
Construction: Worked in flat rows using a simple back-and-forth technique
Finished Dimensions & Sizing: 4 inches by 4 inches

Materials & Supplies Needed

Yarn: Worsted #4 weight, 100% cotton yarn (approximately 15–20 yards per coaster). Cotton is preferred for its heat resistance and absorbency.
Hook Size: 5.0 mm / H-8
Notions: Tapestry needle for weaving in ends, sharp scissors.
Safe Yarn Substitutions: Acrylic yarn can be used if heat resistance is not a priority, though it will not absorb condensation as well as cotton. Wool is a viable alternative but should be hand-washed carefully to prevent felting.

Stitch Guide & Abbreviations (US Terms)

ch = chain
sc = single crochet
st/sts = stitch/stitches
sk = skip
Moss Stitch: A combination of single crochet and chain stitches where the single crochet is worked into the chain space of the previous row.

Step-by-Step Pattern Instructions

Coaster Body

Row 1: Ch 17. Sc in 4th ch from hook, *ch 1, sk 1 ch, sc in next ch; repeat from * across. Turn. (8 sc, 7 ch-1 spaces)
Row 2: Ch 2, sc in first ch-1 space, *ch 1, sk next sc, sc in next ch-1 space; repeat from * across, ending with a sc in the turning chain space. Turn. (8 sc, 7 ch-1 spaces)
Rows 3-14: Repeat Row 2 until the piece measures 4 inches square.

Border & Finishing

Border: Work 1 round of sc evenly around all four sides of the coaster, placing 3 sc in each corner to ensure the piece lays flat.
Finishing: Fasten off, leaving a 6-inch tail. Use your tapestry needle to weave the tail back and forth through the stitches on the back side of the coaster to secure it. Trim any excess yarn.

Care & Washing Instructions

Machine wash your cotton coasters in cold water on a gentle cycle to maintain fiber integrity.
Lay the coasters flat on a clean towel to air dry, reshaping them with your hands while damp to ensure square edges.
Do not bleach or iron the coasters, as this can degrade the cotton fibers and cause the stitches to lose their definition.

Pro Tips & Common Mistakes to Avoid

Check your tension periodically; if your foundation chain is too tight, the coaster will pucker. Using a hook half a size larger for the starting chain can prevent this issue.
Place a stitch marker at the beginning of each row to help keep track of your stitch count, especially when you are just beginning to learn the moss stitch.
Weave your ends in by splitting the plies of the yarn with your needle; this makes the tail nearly invisible and much more secure than simply sewing it into the edge.
To adjust the size, simply increase or decrease your starting chain by an even number; remember that each additional 2 stitches add roughly 0.5 inches to the final width.

Frequently Asked Questions

Can I use a different yarn weight for this pattern?

Yes, but changing the yarn weight will significantly alter the finished size. Using a sport-weight yarn with a smaller hook will result in a much smaller coaster, while using a bulky-weight yarn will create a larger mat.

Is this pattern suitable for complete beginners?

This pattern is ideal for beginners because it only requires the single crochet stitch and chain stitches. Once you understand the rhythm of the moss stitch, the pattern becomes very intuitive.

Are the finished coasters machine washable?

Yes, provided you use 100% cotton yarn. Cotton is durable and handles repeated washing well, making it the perfect choice for kitchen and dining accessories.

May I sell the coasters I make from this pattern?

You are welcome to sell physical items made using this pattern, provided you credit the design. Please do not redistribute the pattern text or photos as your own work.
