This weighted blanket feels like a warm hug because of the interlocking front and back post stitches that create a dense, squishy fabric. The thick ridges mimic a woven basket, making it a heavy piece that holds heat well during colder months. It suits anyone who enjoys repetitive motion for relaxation while building a piece of decor that lasts for years. You will learn how to alternate post stitches to build the signature grid texture without creating holes. This project is a rewarding way to use up soft worsted yarn, resulting in a timeless blanket that adds character to any living room sofa or bedroom chair.

Why You’ll Love This Pattern

This beginner-friendly crochet coaster pattern uses a simple, repetitive stitch pattern that makes it ideal for practicing tension control and even edges. Because each coaster requires only a small amount of yarn, it is a practical project for using up leftover cotton scraps from larger baskets or blankets. The finished items have a dense, durable texture that protects wooden tables from moisture rings, and the final look is clean enough to work well as a thoughtful, handmade gift for housewarmings or birthdays. You can complete a full set of four in a single afternoon while listening to a podcast or watching television.

I loved how quickly these worked up. I made a set of six in an hour and they hold their shape perfectly even after being washed.

Pattern Overview & Skill Level

Skill Level: Beginner
Approximate Time: 15 minutes per coaster
Construction: Worked in joined rounds, starting from the center and expanding outward
Finished Dimensions: 4 inches in diameter

Materials & Supplies Needed

Yarn: Worsted weight (#4) 100% cotton yarn. Approximately 15 yards per coaster. Cotton is essential here because it is heat-resistant and absorbent.
Hook Size: 5.0 mm (H-8) crochet hook.
Notions: Tapestry needle for weaving in ends, a pair of scissors, and optional stitch markers.
Safe yarn substitutions: You may use a bamboo-cotton blend for a softer feel, though this may make the coaster slightly less absorbent. Avoid acrylic yarns as they do not absorb moisture well and can melt if placed under hot mugs.

Stitch Guide & Abbreviations (US Terms)

ch = chain
st/sts = stitch/stitches
sl st = slip stitch to join
sc = single crochet
inc = increase: work 2 sc in the same stitch
dc = double crochet
MR = magic ring

Step-by-Step Pattern Instructions

Coaster Body

Rnd 1: Start with a MR. Ch 2 (counts as first dc), work 11 dc into the ring. Join with a sl st to the top of the ch-2. (12 sts)
Rnd 2: Ch 2, dc in the same st as joining, 2 dc in each remaining st around. Join with a sl st to the top of the ch-2. (24 sts)
Rnd 3: Ch 2, 2 dc in the next st, *1 dc in the next st, 2 dc in the next st; repeat from * around. Join with a sl st to the top of the ch-2. (36 sts)
Rnd 4: Ch 1, sc in each st around. Join with a sl st to the first sc. (36 sts)

Finishing

Fasten off your yarn, leaving a 4-inch tail. Use the tapestry needle to weave the tail through the back of the stitches to secure it firmly. Pull the starting tail at the magic ring tightly to close any gap in the center before weaving it in on the reverse side of the coaster.

Care & Washing Instructions

Machine wash your cotton coasters on a gentle cycle in cold water.
Lay the coasters flat on a clean towel to dry completely.
If the coasters lose their circular shape, dampen them slightly and press them under a heavy book to flatten.

Pro Tips & Common Mistakes to Avoid

Keep your tension consistent throughout every round to ensure the coaster lies flat rather than cupping or ruffling. If the coaster begins to curl, your tension is likely too tight; try going up one hook size. Always place a stitch marker in the first stitch of each round to keep track of where the round begins and ends, which prevents accidentally adding extra stitches. You can easily adjust the size of these coasters by adding an extra round of increases, such as working a repeat of 1 dc in the next 2 sts, 2 dc in the next st for Round 4, but be aware that this will require approximately 5 extra yards of yarn per coaster.

Frequently Asked Questions

Can I use acrylic yarn for these coasters?

It is not recommended. Acrylic yarn is synthetic and does not absorb liquid, meaning moisture will simply sit on the surface of the coaster rather than being wicked away from your furniture. Additionally, acrylic can melt if you place a very hot mug on it.

Why is my coaster curling into a bowl shape?

Curling usually happens because your tension is too tight or you have missed an increase. If your coaster is cupping, check your stitch counts for each round to ensure you have made the correct number of increases as directed.

Can I sell the coasters I make from this pattern?

Yes, you are welcome to sell finished items made from this pattern. Please credit the design to this tutorial when listing your products online or at craft fairs.

Is this pattern suitable for someone who has never crocheted before?

This is an excellent project for a complete beginner. It focuses on basic stitches—the single crochet and double crochet—and uses a simple circular increase method that is foundational for many larger crochet projects.

Seeing the geometric pattern emerge as you work is the most satisfying part of this project. You can change the final appearance by using a variegated wool yarn to highlight the three-dimensional depth of the weave or adjust the dimensions to create a smaller lap throw. Post a photo of your finished work on social media so others can see how the stitches catch the light.
